## Question

### Solution

Correct option is

A parallelogram is formed by choosing two straight lines from the set of mparallel lines and two straight lines from the set of n parallel lines.

Two straight lines from the set of m parallel lines can be chosen in mC2ways and two straight lines from the set of n parallel lines can be chosen innC2 ways. Hence, the number of parallelograms formed.
