Step 1: Change Anu’s position
Now, U is at position 2 (second from left).
Step 2: Change Aishwarya’s position
A is at position 4 (second from right).
Step 3: Apply R and U together rule
If U is at position 2, R must be either position 1 or position 3. But if R is at position 1, then M must avoid sitting next to R — possible. However, we also must place A at position 4. The only way to keep R and U together with U at position 2 is to put R at position 3.
Step 4: Apply M’s restriction with R
If R at position 3, M cannot be at position 2 or 4. Position 2 is U already, position 4 is A, so M can be placed safely at position 1 or 5.
Step 5: Extreme right placement
Remaining person after placing A, U, and R is M and S. If M is at position 1, then S takes position 5 (extreme right). But this puts S next to A (positions 4 and 5), and A-S adjacency is forbidden — so this is invalid.
Therefore, M must be at position 5 (extreme right). But option list suggests Rachel at extreme right, so let’s check: If R were at position 5 instead, then U at position 4 — but U fixed at position 2. So the only arrangement consistent with all is: Pos 1: S, Pos 2: U, Pos 3: R, Pos 4: A, Pos 5: M. Wait — that makes M at extreme right, not R. So the correct answer is actually (d) Manpreet.
