उत्तर और व्याख्या · explanation in English
Answer: (b) केवल I और III
B cannot be in Y or with A in X, so B joins C in Z. E and G ride alone together, which leaves them car Y; D and F then fill X with A. So cars are X: A, D, F; Y: E, G; Z: B, C — D is not the only one with F, since A is there too.
- B is not in Y and not in X (A is in X and A, B are apart), so B is in Z with C.
- E and G travel together with nobody else; X has A and Z has B, C, so E and G take Y.
- X has A and two others: the only ones left are D and F.
- Cars: X = A, D, F; Y = E, G; Z = B, C.
- I true (no car has one person); II false (A also travels with F); III true (Z has only B and C).
- ✓ I Each car carries two or three persons.
- ✗ II F shares car X with both A and D, so D is not the only one.
- ✓ III Car Z carries only B and C.
