What is a herbicide?

A) A type of pesticide application equipment using water under pressure.
B) Breakdown of a chemical in the presence of water.
C) A pesticide used to control weeds.
D) Filters installed in the ventilation system that remove particles.

The correct answer is: C) A pesticide used to control weeds.

A herbicide is a type of pesticide specifically designed to control or eliminate weeds. Herbicides are chemicals or biological agents that target unwanted plant growth without harming desired plants. Therefore, the correct answer is option C - "A pesticide used to control weeds." Option A describes a type of pesticide application equipment known as a sprayer or a spray rig that applies pesticides using water under pressure, but it is not the definition of a herbicide. Option B refers to the breakdown of a chemical in the presence of water, a process known as hydrolysis, which is not specific to herbicides. Option D describes filters installed in ventilation systems that remove particles, which is not related to herbicides either.
