Correct option is C
Given:
Keshav starts from Point A and drives 22 km towards the South.
He then takes a left turn, drives 24 km, turns left and drives 27 km.
He takes a final left turn, drives 5 km and stops at Point P.
Solution:

Distance = 25 km - 24 km = 1 km
1 km is Point 'P' to Point 'A'.
(All turns are 90 degrees turns only unless specified)
Then,
1 km to the east he drive in order to reach Point A again.
