Question

what is the advantage of using glyphosate (roundup) as an herbicide? it promotes the growth of all plants. it will biomagnify in the food chain. it kills plants without affecting the soil. it is entirely safe for the environment.

Explanation:

Glyphosate (Roundup) is a herbicide. Its main function is to kill plants. Option A is wrong as it's a herbicide, not a growth - promoter. Biomagnification (Option B) is a negative environmental impact, not an advantage. Option D is incorrect as it's not entirely safe (has some environmental concerns). Option C is correct as it can target plants while having relatively less impact on the soil compared to some other more soil - disruptive methods.

Answer:

C. It kills plants without affecting the soil.
