Answer:
b. temperament
Step-by-step explanation:
Temperament is a term used to describe how an individual exhibit inborn traits in response to their environment or world. Temperament is usually innate or unlearned but can be shaped over time.
A child can be said to have an easy temperament if the child has a general disposition of a positive attitude and easily adapts to new experiences, or referred to as a difficult child, if the child displays negative attitude and doesn’t adapt easily to new experiences. Slow-to-warm children are inactive with a general negative mood, and adapt slowly to new situations or even withdraw from such. They show a relatively calm response to their environment.
