Answer: Option (A) is the correct answer.
Explanation:
Vitamins are the organic compounds which are necessary for normal growth and provide nutrition to the body.
Vitamins help in conversion of food into energy and repair cellular damage.
For example, Vitamin C helps in boosting immune system. Vitamin B6 helps in the biochemical reactions occurring in the immune system.
Thus, we can conclude that out of the given options, the statement Vitamins help produce the immune response is most accurate.
The most accurate statement about vitamins is vitamins help produce the immune response. (Option A)
Vitamins play a crucial role in supporting the immune system by promoting the production and functioning of immune cells, aiding in the synthesis of antibodies, and assisting in the maintenance of overall immune health.
They act as cofactors or coenzymes in various biochemical reactions that are essential for the immune response.
While all vitamins are important for overall health, certain vitamins, such as;
are particularly known for their immune-supporting properties.

The atmosphere extend from the Earth up to 10,000 km.
An atmosphere is the layers of gases surrounding a planet Earth. It's atmosphere is composed of about 78% nitrogen, 21% oxygen, and other gases.
Earth's atmosphere has five major layers. From lowest to highest, the layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere.
The exosphere is the topmost layer of Earth's atmosphere . It extends from the end of thermosphere, about 700 km above sea level, to about 10,000 km.
Thus, the atmosphere extend from the Earth up to 10,000 km.

The exosphere is the outermost layer of Earth's atmosphere (i.e. the upper limit of the atmosphere). It extends from the exobase, which is located at the top of the thermosphere at an altitude of about 700 km above sea level, to about 10,000 km (6,200 mi; 33,000,000 ft) where it merges into the solar wind.
B) faster through steel than through air
C) faster through air than through steel
D) through steel and air at similar speeds
Answer: The correct answer is Option B.
Explanation:
Sound waves are a type of longitudinal waves. These waves are the waves in which particles of the medium travel in the direction of the wave. These waves require a medium to travel.
Sound waves travel faster in solids than in the gaseous medium because the particles in solid state lie close to each other and the vibrations of the sound waves travel faster when the particles lie closer to each other.
Hence, the correct answer is Option B.
