All of the following imaginary planets were the same distance from the sun which would experience the strongest force of gravity due to the sun?

They are all the same distance so it would not affect gravity on any of the planets.

Hope it helps.

The answer is c, i, iii, and iv. this is because farming and mining deal with harvesting raw materials, construction work falls under manufacturing, and piloting a plane is a service. ii is wrong because making bread is using  raw materials to produce goods, which would fall under the secondary sector, not primary.
