The result of ash, cinders, and bombs building up in a steep pile around a volcano's vent is a cinder cone volcano, so the answer is a.
A cinder cone volcano, also known as a scoria cone volcano, is a type of volcano that forms from explosive eruptions. These eruptions eject lava fragments such as ash, cinders, and bombs into the air.
The fragments cool and solidify in the air before falling back to the ground, forming a cone-shaped hill around the volcano's vent.
Cinder cone volcanoes are typically smaller than other types of volcanoes, and they can be found all over the world. They are usually steep-sided, with a bowl-shaped crater at the top. The height of a cinder cone volcano can vary greatly, ranging from tens to hundreds of meters tall.
One of the defining features of cinder cone volcanoes is their composition. They are made up of loose volcanic material such as ash, cinders, and bombs, which are all fragments of volcanic rock. These materials are typically dark in color and can be very porous, making them easy to erode over time.
In summary, cinder cone volcanoes form from explosive eruptions that produce ash, cinders, and bombs that pile up around the vent, forming a steep cone-shaped hill. These volcanoes are typically smaller than other types of volcanoes and are composed of loose volcanic material.

When ash, cinders and bombs build up in a steep pile around a volcano's vent, the result is a composite volcano.
Further Explanation:
A volcano is an open pore in the earth's crust from which the molten rocks, gases and debris appear on the surface. The volcanoes can be categorized into four types namely composite volcanoes, cinder cones, dormant volcanoes and shield volcanoes.
Cinder cones are the volcanoes that are made up of particles and lava that escapes out of the crust from one vent. These are the simplest form of volcano. When the lava is erupted out of the earth's crust, it is blown into the air and broken into fragments that can further solid define and fall as cinders around the vent. The shape can either be and oval cone or a circular cone. Most of the cinder cones are in shape of a bowl with an average depth of about 1000 feet or less.
Composite volcanoes are those volcanoes which are very steep and symmetrical. The center vent of the volcano is filled with lava and the crest is composed of layers of lava, cinders, blocks, bombs and volcanic ash. Composite volcanoes become dormant and then the cone is destroyed.
The shield volcanoes are totally made up of the lava flows. The lava that comes out of the vent flows in all directions and a broad gently sloping come is formed.
Thus, when ash, cinders and bombs build up in a steep pile around a volcano's vent, the result is a composite volcano.

Answer: The environmentalists are concerned about the introduction of genetically engineered trees because their introduction into the environment could have unexpected interactions with the other plants and animals present in the ecosystem.
Other reason can be loss of native species. The native species that is originally present in the environment can be lost due to the introduction of genetically engineered plant species.
