(E) is the answer

Correct Answer - D
By 1970, rampant whaling had reduced the population of humpback whales to ten percent of its original size. In response, a worldwide moratorium on whaling was enacted. By 2009, the population had largely recovered, and the moratorium was eased in a few restricted areas. During the 2010s, reports of ships encountering humpback whales on the open increased in comparison with the reports in the 2000s. Therefore, despite whatever whaling took place, the humpback whale population must have increased considerably during the 2010s.
Argument = bold italics
Which of the following, if true, most seriously weakens the argument?
A. Throughout the 2010s, the sale of products derived from humpback whales was more strictly regulated than whaling was.
Irrelevant since the argument considers whaling and increase in whale population, sale of products is not relevant
B. The whaling restrictions applied to both private and government whalers.
Irrelevant, this does not affect the argument
C. Humpback whale sightings in coastal regions increased in number, greatly, during the 2010s.
Reiterates one of the facts, does not give us any additional information to weaken the argument
D. There were significantly greater number of ships in the sea in the 2010s than in the 2000s.
If the ships were greater, chances of whale sightings would increase, hence this could weaken the argument
E. Most humpback whale sightings on the open sea in the 2010s occurred in regions where there were very few ships.
Strengthens the argument instead since fewer ships & more sightings
