Answer:
The answer is D. Only de Vaca and the sailing master were capable of manning the ship.
Explanation:
When something is "implied" you are not offering much information as for; why is that true? On the other hand, when you are being explicit or something has explicitly told, that means exactly the opposite of implicit; you have enough information and there's no room for uncertainty. In this context, the three first options give you descriptions and causes and effects; adjectives: cold, stormy, bad. Why did Vaca's crew almost decimated? For the lack of food and bad weather. Thus, option D is the most suitable as we do not know why only Vaca and the sailing master were capable of manning the ship.
