Answer

Brief Explanations:

Exocrine glands secrete substances through ducts that open directly or indirectly to the external environment. For example, sweat glands secrete sweat to the skin - surface (external environment). The first option describes endocrine glands, the second is incorrect as ducts open to external not internal environment, the third is wrong as they do secrete substances, and the fifth describes endocrine (duct - less) glands.

Answer:

Exocrine Glands have secretions that leave through a duct that opens directly, or indirectly, to the external environment.
