2. composite
3. cinder cone
a very tall and broad-sloped peak made of mostly lava flow
a very tall, steep-sloped peak made of both lava and volcanic materials
a shorter peak made of ash and volcanic rock
1. Shield -a very tall and broad-sloped peak made of mostly lava flow
2. Composite- a very tall, steep-sloped peak made of both lava and volcanic materials
3. Cinder cone- a shorter peak made of ash and volcanic rock
Volcanic mountains: Shield: A very tall and broad-sloped peak made of mostly lava flow, Composite: A very tall, steep-sloped peak made of both lava and volcanic materials, Cinder cone: A shorter peak made of ash and volcanic rock.
Volcanic mountains are formed through volcanic activity, where molten rock, gases, and ash are ejected from a vent or opening in the Earth's crust.
When lava flow and make a very tall and broad-sloped peak-like structure, then it is known as a shield. When a very tall and steep-sloped peak structure is made of both lava and volcanic material, it is called a composite. When ash and volcanic rock make a shorter peak, then it is called cinder.

Answer : The correct answer is -
Insertion mutation.
An insertion mutation can be described as a permanent change in the genetic material (DNA sequence) due to the addition of one or more nucleotides. It can result in alteration of protein (due to the change in the reading frame of DNA) , which may cause diseased condition.
In the given question, there is addition/insertion of T (thymine) at the second place in the original DNA sequence-
Original DNA sequence -
ACGTTCATT
Mutated DNA sequence - ATCGTTCATT
Thus, it is an insertion mutation.
