Answer:
Planet B
Explanation:
Planet B will take more to time to complete its revolution because it is farther to the sun. The shorter planet completes its revolution faster due to its short orbit around the sun. This implies that planets that are close to the sun have shorter time to complete their revolution but those far away will take more than usual.
When two tectonic plates push towards each other, one continental, and another oceanic, the oceanic plate is subducting under the continental plate. This is due to the fact that the oceanic plates's crust is weaker and has lesser density, while the continental is stronger and has bigger density, so when pushing against each other, the weaker, less dense, oceanic plate can not oppose the stronger, more dense, continental plate and slowly subducts under it.
