The statement suggests that exposing the skin to sunlight for extended periods leads to the production of more pigment by the skin cells, resulting in tanning. This change in skin color provides evidence for certain conclusions. Let's break down the options:

1) Ultraviolet light can cause mutations: This option is not directly supported by the given information. While it is true that ultraviolet light can cause mutations in DNA, the statement does not explicitly mention this as the cause of the change in skin color.

2) Gene action can be influenced by the environment: This option aligns with the given information. The statement implies that the environment (sunlight exposure) influences the production of pigment by the skin cells, leading to tanning. This suggests that gene action, specifically the genes responsible for producing pigment, can be influenced by the environment.

3) The inheritance of skin color is an acquired characteristic: This option is not supported by the given information. The statement describes a temporary change in skin color due to exposure to sunlight, which does not imply that the change is inherited or permanent.

4) Albinism is a recessive characteristic: This option is not directly related to the given information. Albinism is a genetic condition characterized by the absence of pigment in the skin, hair, and eyes. The statement does not provide any information about albinism or its inheritance.

Based on the given information, option (2) "gene action can be influenced by the environment" is the most supported conclusion.
