  1. All film directors are film stars
  2. All film stars are playback singers.


$A \implies B$ and $B \implies C$ means $A \implies C.$ So All film directors are playback singers.

Conclusion 2 is also true as even if one film director exist, he must be a film star. (We have to assume domain sets to be non-empty here)

Correct Answer: Option D
