So the question is asking percentage increase (and not percentage change phew!) so we need to have an increase as compared to previous year.
So basically first year (85) cannot be an option since I don't have anything to compare it to.
86 and 87 both saw a decrease as compared to previous year.
88 saw an increase of 60%. 89 and 90 cannot match to a 60% increase.
Hence C
