Class : Class 6
the answer is not A nor B,C or D

Ans 2:

Anahita Saxena from Ryan International School Pune, Pune
Class : Class 3
Look here there is some problem. The correct answer is not there. Amrit is right. but all are not wrong. Anand and Rajesh are wrong. So, the correct answer will be E (which is not there actually. I made it myself because the correct answer was not there.) Rajesh and Anand.

Rajesh and Anand are wrong I emphasis more about Anand because the tough material in the teeth is it's enamel not the dentine.

PARTH PANCHAL from NEW HORIZON SCHOLARS SCHOOL, THANE
Class : Class 7
nknnnk

Ans 11:

Kishore Kadiyala from NPS, BANGALORE
Class : Class 5
the correct answer is c because premolars and molars are a set of permanent teeth only.

Ans 12:

Punyatoya from Harvest, Bengaluru
Class : Class 8
All the teeth have root,crown,neck but their SHAPE is different so Anand is correct.

Ans 13:

Advika Narkar from The Shishukunj International School, Jhalaria Campus, Indore
Class : Class 8
I agree with the solution given. Anand is right as a tooth also includes dentine as well as enamel. If it would have been,'The covering of a tooth is dentine.',it was wrong. Bhavya Jain check the solution.
