Answer

Answer: Option B

Solution

Answer: Option B
Solution:
The non-preference plant resistance to insects is also known as Antixenosis.
Nonpreference refers to various features of the host plant that make the host undesirable to insects for food, shelter, or reproduction. It is also termed antixenosis.
Antixenosis occurs when there is non-preference for the resistant plant compared to a susceptible one. When the life-history parameters (survival, development, fecundity) of the insect are affected, the term antibiosis can be applied.
