Answer;
Both genes and the environment
Both genes and the environment direct and produce human behaviors, personality traits, and even psychological disorders.
Explanation;
-Human behavior is determined by complex interactions of both nature and nurture. Genetic make up of a person together with the environment influences the physical and behavioral characteristics of an individual.
-Personality is a complex trait that is influenced by many different genetic and environmental factors. Personality traits are also polygenic trait because multiple genes are involved in determining these traits.

I thought it was (d) but I might be wrong
Answer:
Correct
Explanation:
Homeostatic is nothing but ability of a system or living organism to manipulate its internal environment to maintain a stable equilibrium, for example the ability of warm-blooded animals to ascertain a constant body temperature.
The Homoeostatic feedback mechanism has three basis components and they are independent to one another.
These components are receptor, effector and integrating center. The function of receptor is to sense external stimuli and send information to integrating center. The integrating center generally hypothalmus in brain sends this signal to effector for example an organ to react to the stimuli.
So, the order in a homeostatic feedback system stimulus, receoptor, control centre, effector is correct.
