A15 km towards the north
B12 km towards the north
C3 km towards the south
D12 km towards the south ✓ Correct
Correct answer: (D) 12 km towards the south — Town B is 12 km towards the south of town C, so that is the answer.
Explanation
★Town B is 12 km towards the south of town C, so that is the answer.
★Take town A as the origin, so town D is 12 km north of A.
★Town C is 15 km west of D, and town B is 15 km west of A.
★So B and C are both 15 km to the west, lying on the same vertical line.
★C is at the level of D, which is 12 km above A, while B is at the level of A.
★So B is 12 km to the south of C.
