The assertion states that the pineal gland is situated on the epithalamus of the diencephalon, which is correct. The pineal gland is located in this region of the brain.
However, the reason provided states that the pineal gland is an exocrine gland that exhibits activity primarily during the later stages of life is incorrect. The pineal gland is not classified as an exocrine gland. Instead, it is an endocrine gland that secretes melatonin, a hormone involved in regulating sleep-wake cycles and other physiological processes. The activity of the pineal gland, including melatonin production, is not limited to later stages of life but occurs throughout a person's lifespan.
Therefore, while the assertion is true, the reason is false, making option 3 the correct answer.
