If Earth were much bigger, the gravitational force between Earth and the Moon would be higher.
If Earth were much bigger, the gravitational force between Earth and the Moon would be lower.
If Earth were much bigger, the gravitational force between Earth and the Moon would not change.
If Earth were much bigger, the gravitational force between Earth and the Moon would disappear.

Answer 1

If Earth were much bigger, the gravitational force between Earth and the Moon would be higher.

Reason: Newton's law of gravitation says F = G m1 m2 / r^2, so force increases with mass and decreases with distance.
