According to the biological approach, which of the following factors is considered to influence behaviour?

• A. Genes
• B. Brain structure and nervous system
• C. Hormones and neurotransmitters
• D. All of the above

Answer: (D)

In the biological view of psychology, behaviour is shaped by multiple interacting biological processes. Genes provide inherited instructions that can influence traits and predispositions. Brain structure and the nervous system determine how information is processed, decisions are made, and responses are coordinated. Hormones and neurotransmitters regulate neural activity, affecting mood, arousal, motivation, and behavior. Because these elements work together—genetic influences shaping brain development, brain activity affecting chemical balance, and chemicals modulating neural function—the factors listed all contribute to behaviour. So the best answer is that all of the above influence behaviour.
