Astronaut being weightless is irrelevant, it's mass that accounts for gravitational force

The answer is definitely C; equal and opposite forces :-)

Y’all ain’t built for physics, huh?

Explain? If both applied the same force to each other, wouldn’t their accelerations towards each other also be identical?

No. F=ma. The gravitational force is always equal and opposite between two objects. So since the earth's mass is so large, the acceleration will be so small. But the product of the two will still be equal to the product of the astronaut's small mass and large acceleration

If they were equal masses then the acceleration would be equal and they would move towards each other equally. But the masses are different.
