Ans. (B). Genes.
The chemicals that kill the weeds are known as herbicides. Herbicide-resistance is defined as the inherited ability of weeds to survive an application of herbicide, that can kill a normal weed plant of same species.
The resistance develops due to mutations in genes that were sensitive to those chemicals in wild-type forms. As genes are responsible for transfer of characteristics from one to another generation, the herbicide-resistance is also passed down to generations through genes.
Thus, the correct answer is option (B).
Cohesion occurs when molecules of the same substance are attracted to each other.

This is because Earth's rotation generates what is known as the Coriolis effect. This effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
