The gene that is most likely to be widely expressed in response to a superficial scrape is the one that controls the production of skin cells. This is because skin cell production is crucial for the repair process following an injury. Therefore, the correct answer is option B.
;
The most likely gene to be widely expressed in response to a superficial scrape is the one that controls the production of skin cells. These genes help repair the outer layer of the skin, making them critical during the healing process. Other gene types, like those for red blood cells or cardiac cells, are not directly involved in skin repair. ;
