B.latent                            
Explanation:
According to Sigmund Freud, there are two distinct types of dream content including, manifest content and the latent content. He argued that an individual's dream represents his or her disguised fulfillment or completion of a particular repressed wish and it provides the way of understanding the unconscious feelings or activities of an individual's mind.
Latent content: In psychology, the term latent content is defined as an individual's hidden dream aspect that describes a psychological meaning of his or her dream. It generally appears in a symbolically disguised way. The latent content of an individual's dream encompasses things that are hidden from the person's conscious awareness.
