Along the mudflats of Garantia, exist two types of annelids: earthworms and lugworms. Earthworms tend to emerge from the mud early in the morning when there is more moisture and nutrients. As a result, earthworms have access to more nutrients and thus reproduce far faster than the lugworm, which spends much of the day submerged in the mud. Nonetheless, the lugworm population far outnumbers that of the earthworm.

Which of the following, if true, helps LEAST to resolve the apparent discrepancy noted above?

(A) Lugworms have specialized taste receivers, which allow them to access nutrients below ground far more easily than earthworms can.

(B) The whooping crane, the earthworm’s chief predator, hunts along the mudflats during the time the earthworms are feeding at the surface.

(C ) Lugworms resemble the color of the mudflat, and are thus more difficult to spot by predators than earthworms are.

(D) Compared to the lugworm, earthworms are able to consume fewer nutrients at one time.

(E) Lugworms tends to emerge in the evening, when the number of predators is less than during the early morning hours, when the earthworm is exposed on the mudflat.

Pre-thinking: Lugworms should be having some capability/process through which they are getting nutrients and are able to maintain & increase the population. Or some external factor is responsible for reducing the earthworms population.

Now let's have a look at the options. The option which is deviating from our pre-thinking is our answer.

(A) Lugworms have specialized taste receivers, which allow them to access nutrients below ground far more easily than earthworms can..........................It matches our pre-thinking. Therefore, it's not the least helpful.

(B) The whooping crane, the earthworm’s chief predator, hunts along the mudflats during the time the earthworms are feeding at the surface.........................Matches our pre-thinking.

(C ) Lugworms resemble the color of the mudflat, and are thus more difficult to spot by predators than earthworms are..................................again, it matches our pre-thinking.

(D) Compared to the lugworm, earthworms are able to consume fewer nutrients at one time..................It's not matching with our pre-thinking. Therefore, it's least helpful in resolving the discrepancy

(E) Lugworms tends to emerge in the evening, when the number of predators is less than during the early morning hours, when the earthworm is exposed on the mudflat.........................Somewhat matches with our pre-thinking
