Correct answer: B
Correct answer: constant
Newton's second law in momentum form is F = dp/dt, where p is momentum and t is time.
If the net force is zero, then dp/dt = 0. This means momentum is not changing with time.
So, the body's momentum remains constant. It may be zero or non-zero depending on its initial motion.
