Answer 1

Answer: (B)

Either A alone or B and C together are sufficient

According to A:

From bottom: Nitin ( 13th rank)

Bhupesh (7th rank) [ as nitin is six rank ahead of Bhupesh]

Suresh (9th rank)

So we can calculate the rank of Suresh.

According to B and C :

Kamlesh (15th rank)

Bhupesh(11th rank) as four rank ahead of kamlesh)

and Suresh (9th rank).

So we can calculate rank of Suresh by both B & C together.

Hence option B is correct.
