Answer:
B) Both peanuts and nuts can cause allergies
Step-by-step explanation:
In the 2nd sentence it says '...both of them can cause allergic reactions in some people...'. n the first sentence it states that peanuts are not nuts and later on it states they are legumes, This fact does not support options A or C. It also states that peanuts grow underground, so D is not an option. This leaves us with B.
