Which of the following usually does not impact agricultural production and consumption?

A.

disease

B.

the availability of arable land

C.

supply and demand

D.

infrastructure

I believe that the option that does not usually impact agricultural production and consumption is D. infrastructure, whereas disease, the availability of arable land, and supply and demand do.

But then again, I'm not sure whether you are referring to the disease of the land or the people.
