(a) the momentum is conserved - Yes, it is conserved however it is continuously increasing as the body moves under acceleration.
(b) there is zero net force acting on it - No If it did the fall would be no fall at all and the free fall body is moving with acceleration
(c) equal distances are traveled in equal times - No. The body is moving will acceleration.
(d) only the gravitational force is considered - It depends. In vacuum perhaps it is true, however frequently we must take the air resistance into consideration.
