Explanation:

  • S1: C is younger than D, but older than A and B.

Answer: Option D, S1 and S3 together are sufficient to answer the Question.

Explanation:

  • From S2, we know that D is the oldest.

  • From S1, we know that C is younger than D, but older than A and B.

  • From S3, we know that A is older than B.

  • So, we can arrange the people in order of their ages as follows: D > C > A > B

  • Therefore, B is the youngest among A, B, C, and D.

Three Statements S1, S2 and S3 are given below followed by a Question:...
Option D is correct because from S1 we can only conclude that D is oldest, C is older than A and B but we can't make any view on Is A older than B or not.
so this info is provided in S3.
therefore, S1 and S2 together are sufficient to answer the question.
