Which of the following is a biological factor influencing mental health?

Genetic predisposition to mental illness is a significant biological factor influencing mental health. This concept refers to the hereditary risk that individuals may carry due to their family history and genetic makeup, which can make them more susceptible to developing certain mental health disorders. Research has provided evidence that specific genes can affect how an individual responds to various environmental stressors, potentially leading to the manifestation of mental health issues.

In contrast, personal beliefs about therapy, family support levels, and coping strategies are primarily psychological and social factors. They contribute to an individual's overall mental well-being but do not fall under the category of biological influences. Understanding the interplay between biological factors, such as genetics, and these other influences is crucial in the context of mental health, as it can help guide treatment and support strategies tailored to individual needs.
