Answer 1

Incisors are narrow edge teeth present at the front of the mouth while canines are pointed teeth and are of great importance in the carnivorous animals. Molar and premolars are not sharp like the incisors and canines.

Complete answer:
A normal adult human has 32 teeth that are made up of dentin and enamel. Human teeth are diphyodont (erupt two times in a lifetime), the codont (covered in the jaw socket), and heterodont (different types of teeth).
Different type of teeth along with their functions are:

(A)Incisors	(3)Cutting teeth- They are four in number and are pointed teeth that work like scissors when upper and lower incisors cut food together.
(B)Canines	(4)Tearing Teeth- Canines are also four in number with the primary function of tearing foods they are sharp and pointy. Two canines are present in the maxillary arch whereas two in the mandibular arch.
(C)Premolars	(2)Crushing teeth- Also known as bicuspids & are located adjacent to canine and help in crushing the food due to its wide diamond shape surface. They are eight in number.
(D)Molars	(1)Grinding Teeth- Molars are the posteriorly located rectangular teeth with pits and fissures, which are helpful in grinding the food. They are twelve in numbers and third molars are also known as wisdom teeth which developed later in life.

So, the correct answer is ‘A-3, B-4, C-2, D-1’.

Note: -Enamel that covers the teeth is the hardest part of the body known.
-Children have 20 primary teeth which fall out at the age of 6-7 years.
