Concept:This is a data sufficiency question based on linear seating arrangement.Explanation:Four people sit in a row facing south. Let the positions from left to right be $1,2,3,4$.Statement I: Bipin is immediately to the right of Arvind. So the pair $(\text{Arvind}, \text{Bipin})$ is fixed in this order.This pair can occupy positions $(1,2)$, $(2,3)$, or $(3,4)$. Hence, the person second from the left is not fixed.So Statement I alone is not sufficient.Statement II: Divyesh is at the extreme right end. This fixes Divyesh at position $4$.The remaining three people can still be arranged in many ways. So Statement II alone is not sufficient.Combining Statements I and II: Divyesh is at position $4$.The pair $(\text{Arvind}, \text{Bipin})$ must therefore occupy either $(1,2)$ or $(2,3)$.If they occupy $(1,2)$, the order is Arvind, Bipin, Chetak, Divyesh; the second from the left is Bipin.If they occupy $(2,3)$, the order is Chetak, Arvind, Bipin, Divyesh; the second from the left is Arvind.Since two different arrangements are possible, the data is insufficient even after combining both statements.Answer:Option B: Data in both statements I and II together are NOT sufficient to answer the question.
