  1. The car moves initially with a constant speed and then slows down
  2. The car accelerates initially and then moves with a constant speed
  3. The car starts from rest and keeps accelerating
  4. The car moves with a constant speed all along

A
The car accelerates initially and then moves with a constant speed
B
The car moves with a constant speed all along
C
The car starts from rest and keeps accelerating
D
The car moves initially with a constant speed and then slows down
Solution
Verified by Toppr

Initially, the drops are at a uniform separation.The rate of dripping being constant, the motion, then, is with a constant speed.
Later on, the spacing between the drops keeps decreasing.This means, within same time interval, the car covers lesser distance as the time progresses.
So, later, the car slows down.
