Which of these describes a mucous secretion feature of certain glands?

The term that accurately describes a mucous secretion feature of certain glands is "lactiferous." This term is specifically used to refer to ducts that convey milk from the mammary glands, indicating a secretion that is distinctly fluid in nature. In the context of glands, "lactiferous" signifies a function that is integral to lactation and highlights the secretion of a substance that can be classified as mucous due to its viscous quality.

Other terms provided do not pertain to mucous secretions from glands. "Knismogenic" relates to the sensation of tickling or itching and does not describe glandular secretions. "Kraurosis" is a medical term generally associated with the atrophy of tissues, often referring to the vulvar area, rather than describing a type of secretion. "Ketoacidosis" is a serious metabolic condition linked to diabetes and does not pertain to the function of mucous-secreting glands. Thus, lactiferous is appropriately linked to the specific secretions associated with certain glands in the body, particularly those involved in milk production.
