Answer:
Assertion and reason both are true . If we take rocket and fuel as a system then its momentum remains conserved when fuel gases exert from back of rocket then momentum of fuel gas is in opposite direction so to balance it fuel push rocket forward so total momentum remain conserved . It's just like Newton's third law of motion .
