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.

Ans 26:

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.

Rishik De Sarkar from Delhi Public School Gurgaon, Gurgaon
Class : Class 7

Ans 28:

Aarathy Sudhir Aarav Sudhir from Global Indian International School, Abu Dhabi
Class : Class 7
Rajesh and Anand are wrong I emphasis more about Anand because the tough material in the teeth is it's enamel not the dentine.
