Hi,

I hope you are doing well.

I am providing you the link from were you can download previous year question paper:

https://school.careers360.com/cbse/cbse-previous-year-question-papers-class-12

I think you have not mentioned the question properly as you have not mentioned the board about which you want to know the answer. The question seems to be incomplete. So, if you want to know about the previous year's Biology question papers for the class 12th board exam then just mention the board name so that it will be easy for us to answer this question.

Thank You.
