Climate determines all of the following except
a. the price of produce
b. the amount of production
c. what products are cultivated
d. where agriculture is produced

The answer is B. The amount of Production

How climate affects :

The price of produce : The price the produce a fruit Jam in a tropical country will be way cheaper than snow covered country

The products that cultivated : A certain product can only be produced at an area with a certain climate

Where Agriculture is produced : on a tropical Climate agriculture can be produced on the open field, on  a snowy climate it have to be produced in a Glasshouse )

Climate doesn't determine the amount of production. 

The matter of fact is that industry doesn't revolve around climate in the sense that it depends on what the climate is and what an industrial output of products is. These two things are somewhat separate. For that reason, companies can produce the desired amount of products, regardless of the climate.
