Answer:
The sum of kinetic and potential energy will be negative. This is because if the velocity with which the missile is launched is less than escape velocity, then the missile is bound by the gravitational field of Earth. This results in negative total energy. Option B is the right answer.

Answer:
Total energy is zero at infinity. The force acting is attractive, hence the total energy is negative.
