Answer:
if the sun was farther away from Earth
Explanation:
by using the Formula of Universal Law of gravitational F = GM1M2/R² we can deduce the relationship of those symbols
for option 1
when the size increases , the mass also increases. Then the gravitational force increases
for option 2
when the size of Earth increase, the mass increase and thus the gravitational increases.
for option 3
when the distance between sun and Earth increases. The Gravitational Force decrease because F is inversely proportional with R²
for option 4
if the distance between Earth and the sun decrease, the gravitational force increases. then option 4 is wrong
the option 3 is the correct one .
