Central Board Of Secondary Education [CBSE] — Error in Social Science Answer Key-032/1/4

Respected sir/madam I am a student of class 10th studying in CBSE affiliated school.On[protected] we had social science exam. My query is that in the question paper the answers of QUESTION NO. 25 and 35 is option 'B' for both but in answer key the answer is 'A' for both.And also in question number 31 the answer should be 'C' instead of A as reason is wrong.
Sir/Madam now let's take a look at questions

Question no. 25
Assertion- After Russian occupation in Poland, the Russian language was imposed on its people
Reason-the use of polish soon came to be a symbol of struggle against Russian dominance.

Correct Answer Should be 'B' because reason is not explaining the assertion but if we replace their positions then the answer is A
Explanation - Correct line is 'the use of polish soon came to be a symbol of struggle against Russian dominance because after Russian occupation in Poland, the Russian language was imposed on its people.
Here given Assertion (in question) is actually the reason of the given Reason(in question).

Question No. 35
Assertion- majority community is dominant in a few democratic
Reason -dominance can undermine the unity of the country

Correct answer should be option B instead of option A because the reason is not explaining the assertion. So please kindly check this question again.

Question No 31
Assertion- in Britain the formation of nation state was not the result of sudden upheaval.
Reason-ethnic groups of Britain extended its influence.

Here the correct answer of this question should be option C because hair the reason is wrong.
In the provided a reason it is clearly mentioned that the ethnic groups of Britain extended its influence but in real only e English ethnic group extended its influence and in the history NCERT book it is clearly mentioned that if we talk about ethnic groups in in Britain then it will also include the Welsh Scott and Irish community and these other communities did not influenced any movement show the correct answer of this question should be option C.
