Answer 1

Hint: When a snake bites it leaves two spots on the body of the pray.
The spots are nothing but holes that are made by the teeth of the snake.
The poison of the snake is injected into the body of pray by that hole only.

Complete answer: The fangs of a snake are sharp, enlarged maxillary teeth but the maxillary teeth is have some modification in it. So, the assertion is wrong.
The poison apparatus of snakes consist of three parts – a pair of poison-gland, connecting ducts, and a pair of fangs. So, the Reason is correct.
When a snake bites a prey, venom is released immediately and starts working on the nervous system of that pray and within few minutes the pray lost its life or paralyzed.

Thus, the correct answer is option D. Assertion is incorrect but the reason is correct.

Note: The shapes of fangs are sharp, long, hollow, or grooved. The modified maxillary teeth are connected to a small sac in the head of the snake. It is present behind its eyes. Venoms are produced from these sacs. Venoms are poisonous liquid. Nowadays, venom is widely used in research work to identify its medical importance to treat neurodegenerative diseases like Alzheimer’s disease.
