Dear sir/madam
I am a student of class x[protected]. Today was the science paper conducted by CBSE. I humbly request to review the answer key which according to me, is having two mistakes. They are as follows-
1. According to the answer key the answer for question number 31 is option(b) but according to me, the answer should be option(a).
2. According to the answer key the answer for question number 32 is option(c) but according to me, the answer should be option(d).
Thank you
yours obediently
