The learning, in which a new behavior is acquired but is not demonstrated until reinforcement is provided, is known as

Correct option is C

Latent learning refers to the process in which learning takes place, but the knowledge or skills acquired are not immediately evident in the learner's behavior. The learner acquires new information or behavior without it being immediately observable or without any reinforcement being provided at the time of learning. The learned behavior or knowledge is demonstrated later when there is motivation or a need, often in the form of a reinforcement. This concept was demonstrated in experiments by Edward C. Tolman, who found that rats could learn the layout of a maze without any rewards and would demonstrate this knowledge as soon as they were given a reason to do so, such as a food reward at the end.
 Observational learning (Option a) involves learning by watching others, modeling their actions, and observing the consequences of those actions.
 Social learning (Option b) is a broader concept that incorporates observational learning but also includes learning through direct instruction and social interaction.
 Moral learning (Option d) refers to the process by which individuals develop their understanding of right and wrong and acquire moral values.
Therefore, the correct answer is (c) Latent learning, which describes the acquisition of new behavior that is not immediately demonstrated until an appropriate incentive or context arises.
