60% of the vehicles are 4WDs:
60 are 4WDs and 40 are not.

Seven-tenths (70%) of the vehicles were rented:
70 rented and 30 not.

Three fifths of the 4WDs were rented:
3/5*60 = 36 4WDs were rented and 24 not.

So, out of 30 vehicles that were not rented 24 were 4WDs and 6 not: 6/30 = 20%.

Answer: A.
