Assertion (A): Dust particles suspended in the air inside unheated gain electrons can sometimes react explosively.
Reason (R): The dust particles have large surface area for the reaction.

Options

A. Both A and R are true and R is the correct explanation for A
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is true
