Hello. This question is incomplete. The full question is:

"Many of the forests of Virginia have been cleared for farmland. Which of these would least affect the time it would take to return a farm to forest conditions?  A. The number of viable tree seeds on the land  - B. The amount of available nutrients in the soil  - C. The density of the original forest on the farm  - D. The ability of the farmland to retain moisture."

C. The density of the original forest on the farm.

Explanation:

The original forest on a farm is the set of plants native to the place that develops as long as there are conditions for its development in this location. Such conditions are: light, heat, humidity and favorable soils, in which water is essential.

This original forest will be the main factor that would affect less the time needed for Virginia's deforested forests to return to their forest conditions.
