When buying in bulk, you a) buy only those things that are non-perishable b) buy only those things that you know are going to be used quickly or are non-perishable c) buy only those things that you know are going to be used quickly d) buy items sparingly

Option B) buy only those things that you know are going to be used quickly or are non-perishable.    

Step-by-step explanation:

we have to choose the option which i should do when buying in bulk.

As, Non-perishable food items are those food items with a much longer life and don't require refrigeration.

Typically, non-perishable foods include canned goods, dry goods and dehydrated foods.  

Hence, buying in bulk you should buy only those things that are used quickly and don't require refrigeration i.e those items with a much longer shelf life.

∴ Option B is correct

buy only those things that you know are going to be used quickly or are non-perishable.
