Albinism is a rare genetic condition that inhibits the production of melanin, or pigmentation, in the skin and hair. People born with albinism are unusually susceptible to sunburn, melanoma, and a range of other health issues that are generally connected to excessive exposure to the sun. The statements above, if true, provide the most support for which of the following conclusions?

A. People born with albinism develop other biological protections against melanoma and other sun-related health issues.

B. Humans with a high production of melanin can easily ignore health issues related to exposure to the sun.

C. When a non-albino person gets sunburn, the amount of melanin produced by that person decreases.

D. In humans, melanin plays a role in protecting the skin from developing sunburn and other sun-related ailments.

E. It is not possible for a person born with albinism to adopt other artificial protective measures against excessive exposure to the sun.

OPTION A - INCORRECT
This doesn't support the conclusion to the argument because it claims that people born with albinism develop protections against sun related health issues unlike the argument that claims they are susceptible to sun related health issues.

OPTION B - INCORRECT
Well, the argument is concerned about people without melanin, not humans with a high production of melanin. So, this doesn't support the conclusion to the argument because it has deviated from the main subject of the argument.

OPTION C - INCORRECT
This cannot serve as a support to the conclusion of the argument because the argument isn't about a non-albino person, but a person with a person with albinism.

OPTION D - CORRECT
If true that, in humans, melanin plays a role in protecting the skin from developing sunburn and other sun related ailments. It supports the conclusion to the argument because it implies that people without melanin (albinism) are easily affected by the sun which is the directly opposite of it.

OPTION E - INCORRECT
There is no evidence or indication of this in the argument, so it cannot serve as a support to the conclusion of the argument.
