Explanation:

Ants rummage to discover nourishment and take it back to the state. On the off chance that they go over nourishment things that are excessively huge or substantial for a solitary individual to convey, a few species can frame groups to agreeably convey these things to the home. This aggregate route process relies on the navigational capacities of the individual ants.
The direction capacity required of selected people is to follow the aroma of the path, which is kept crisp by the continuous checking conduct of the foragers, as modest drops of the path pheromone are laid on the substrate (e.g., ground, tree trunks).
That is the manner by which the ants manage two contending trails of various lengths; the more drawn out course will turn out to be less and less engaging as an ever increasing number of individual specialists are pulled in by the more grounded smell of the shorter way.
Hence, the right answer is option D "Hypothesize that the ants are following a scent trall that the first ant left".
