• B. Father
• C. Grandfather
• D. Grandfather or Grandmother
• E. None of these

Answer 1

The correct option is D Grandfather or Grandmother

$S$ is the daughter of $P$ and the sister of $T$.

So, $T$ is the daughter of $P$.

Now, the sister of $P$ is the daughter of $M$.

This means that $P$ is also the daughter of $M$.

Clearly, $T$ is the grand daughter of $M$.

So, $M$ is the Grandfather or Grandmother of $T$.

option D.
