Solution

The correct option is B
12

A variable is an unknown quantity whose value is not constant.

In the given equation 2p + 3q + 12pq = 0, "p" and "q" are the variables. "pq" is not considered as a separate variable because, if "p" and "q" are individually found, "pq" can be found. Hence, there are 2 variables in the equation and not 3.
