Answer:

Answer: Option (B)

Explanation: The R-layer represents the unweathered rocks that are located below the surface and is the lowest layer in the soil profile. Here, hard rocks are found which are difficult to break, and are breakable with heavy machineries only. This R-layer makes the foundation of the soil profile that supports the entire overlying series of layers.

Thus, the correct answer is option (B)

Why is innate host resistance a type of nonspecific immune response?.
ASHA 777 [7]

These defenses are described as nonspecific because they do not target any specific pathogen; rather, they defend against a wide range of potential pathogens.

<h3>Is innate immunity nonspecific resistance?</h3>

The innate immune system provides this kind of nonspecific protection through a number of defense mechanisms, which include physical barriers such as the skin, chemical barriers such as antimicrobial proteins that harm or destroy invaders, and cells that attack foreign cells and body cells harbouring infectious agents.

Thus,  they do not target any specific pathogen; rather, they defend against a wide range of potential pathogens.
