Central Board Of Secondary Education [CBSE] — Answer key error

Address:

B

I am a student of standard 10 in Bihar.Yesterday I gave the social science term 1 examination[protected]. I have spotted a few errors in the answer key that you have provided to the schools.
They are as follows:
In question 25 the assertion is explaining the reason and not the other way around hence the answer should be not a) but b).
In question 35 many students and teachers have agreed with me that the answer should be b and not a
In question 38 the answer a/c to the answer sheet is a but actually both the statements are independent of each other plus the Tamils did not have any problem with Sinhala being declared as the national language but the problem began when Tamil was rejected of it's gaining a national status.
And some other students also have complained about other questions and many are confused.
So I humbly request you to recheck the answer sheet or provide grace markings for the students who attempted these questions as this confusion is causing a lot of stress.
