Through the process of watching and imitating another's behavior (D)

Explanation:

observational learning is a learning process that involves separate process combined into one learning outcome and these processes are : attention, retention, production and motivation.

this is a theory that express how one learns a new behavior or action through the observation or imitation of a character exhibiting or demonstrating some form of behavior unusual to the observer. example of such observational learning is a child watching a parent play with a toy and learning/imitating the way the parent played with the toy.

d. through the process of watching and imitating another's behavior.

Explanation:

Observation and imitation learning was studied by Albert Bandura, who in one of his experiences offered a doll to a child and the child did not show any violent attitude. However, after the child watched an adult hitting the doll, he imitated this behavior. Thus, it is the learning acquired through the observation of someone doing something.
