Working: D is in Assam, which is not Arts (Rajasthan) or Science (Kerala), and A has Commerce, so D is at Engineering. The Engineering college is therefore in Assam, and D studies there. B is then at Science and C at Arts.
Why each option is right or wrong
- (a) C is at Arts, not Engineering.
- (b) B is at Science, not Engineering.
- (c) Engineering is in Assam; Gujarat is Commerce's state.
- (d) Correct: D is the only student left for Engineering.
