A body whose momentum is constant must have constant

A body whose momentum is constant must have constant
  1. acceleration
  2. force
  3. velocity
  4. mass

Solution

Momentum of a moving body with velocity $v$ is given as $ p=m v $ Since mass $m$ of a body remains always constant. Hence, if momentum of body is constant, then its velocity must be constant
