Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
0%
Assertion is correct but Reason is incorrect
0%
Both Assertion and Reason are incorrect
Explanation
A faint line runs on either side of the body extending from the head to the posterior end of the tail, this is called lateral line (also called neurotics system). It marks the position of an underlying canal which runs along side of the body and contains special receptor organs. The lateral line canal extends anteriorly into the head, where it branches into several canals; at intervals these canals opens to the exterior through the pores. These canals contain neurotics organs like rheoreceptors or current receptors. The latter can perceive vibration of very low frequency and detect disturbances in water.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.

Female have functional mammary glands.
Explanation
All females of the class Mammalia have mammary glands. The glands produce milk after the birth of offspring. Milk is a nutritious fluid. It contains disease-fighting molecules as well as all the nutrients a baby mammal needs. Producing milk for offspring is called lactation.
Most mammals give birth to live young, but a few (the monotremes) lay eggs.
Mammals can be both herbivorous and carnivorous.
So, the correct answer is option D.
