Deductions from the clues.
Kolkata has Commando and Accountant \(⇒\) \(Q\) (Commando) and \(T\) (Accountant) live in Kolkata. \(T\) is married; \(Q\) is not (Commandos don’t marry).
Teacher lives in Chennai; remaining city after fixing Kolkata (Q,T), Delhi (P), Mumbai (S,U) \(⇒\) \(R\) must be the Teacher in Chennai.
Professions left for \(P\) and \(U\) are Pilot, Banker.
“Two of the unmarried ones live in Kolkata and Delhi” \(⇒\) \(Q\) (Kolkata) and \(P\) (Delhi) are certainly unmarried.
“One of the two Mumbaikars is married” \(⇒\) exactly one of \(S\) or \(U\) is married.
Check options.
(B) True — from above, \(R\) is Teacher in Chennai.
(C) True — \(Q\) is Commando; Commandos do not marry.
(A) False — If the Banker is unmarried it can be \(P\) (unmarried) in Delhi, making \(U\) the Pilot (not \(P\)). A valid assignment contradicts the statement.
(D) False — If the Diplomat \(S\) is married, then (by the Mumbai rule) \(U\) is unmarried. Since \(P\) and \(U\) are \{Pilot, Banker\}, the Banker can be \(U\) (unmarried), violating “then the Banker is married.”
\[ \therefore \boxed{(B)\ \text{and}\ (C)}\ \text{are true.} \]
