Answer:
All of the above is true about the waxing gibbous and waning gibbous moon.
Explanation:
The first option is correct because the waxing gibbous moon is lit up on the right, with the moon moving into full moon phase next, and then being followed by a phase where it is lit up on the left, known as the gibbous waning moon.
The second option is correct because the moon moves from the waxing gibbous phase toward the full moon phase, it is becoming more and more lit up, thus it gains light, while the waning gibbous moon phase comes after the full moon phase where it is becoming less and less lit up, thus loses light.
The third option is correct because the lit up part of the moon in both of these phases has an elliptical shape, with the elongated part being on the top and bottom side, thus giving it an appearance like a football.
