Answer #1

The answer is the first option.

•Sebaceous glands are the holocrine glands that secrete lipid secretions called sebum for lubricating hair shafts and the skin surface.They are mostly present on the face and scalp and to some extent on other parts.

•Merocrine and apocrine glands are exocrine glands that secrete sweat and are different from Holocrine glands.

In merocrine, it is through exocytosis while in apocrine,the apical part of the cell containing the secretions is pinched off.

•Ceruminous glands secrete cerumen or earwax and are present in external auditory canal.

•Mammary gland produces milk.It is a modified sweat gland.
