Correct answer: D

Facing north, the left end is the west end, so Tara is 9th from the west.
Facing south, a person's left hand points east, so the new left end is the east end.
Tara from the east end $= 25 - 9 + 1 = 17$ .

Worth noting

9 assumes the left end stays the same after turning. Left and right belong to the direction the people face, not to the ground.
