Assertion (A): Collisions between two large raindrops can increase the number of drops present.
Reason (R): The impact often produces several satellite fragments rather than a single merged drop.

  • A.A is false but R is true
  • B.Both A and R are true, and R is the correct explanation of A
  • C.Both A and R are true, but R is not the correct explanation of A
  • D.A is true but R is false

Answer: B

Both are true and the reason gives the outcome, and this is collisional breakup viewed from the number perspective. It is one of the processes that maintains the equilibrium spectrum. Breakup is a source of drop number as well as a sink of size.
