Quizplus · Accepted Answer

The hormone leptin is primarily secreted by adipose (fat) tissue and plays a key role in regulating energy balance and body weight. Genetic variations in the leptin hormone and its receptor have been associated with obesity and body weight regulation. Therefore, A appears to be a genetic factor involved in controlling one's weight. The number of sweet receptors on the tongue, chewing rate, and stomach size are not primarily determined by genetics and are more influenced by environmental factors.
