(C) laterline organs
(D) Auditory sense organs​

Answer 1

Answer:

A) Olfactory sense organs

Explanation:

Fish also have another sensory organ called the Lateral Line. A lateral line is a sense organ of microscopic pores used to detect movement and vibration in the surrounding water. Located just under the skin, the lateral line consists of sensory receptors called neuromasts.

The organs of smell or olfactory organs in fish are pouch-like structure that opens to the water through incurrent and ex-current channels, i.e., naris or nares divided by flap of skin. The olfactory pit is internally lined with ciliated epithelium which is projected in multi-folded olfactory rosette of receptor cells.
