Hello Mounika!
It's good that you are asking for answer key for science but please do specify the board like whether it's CBSE or any other state board. Although I am attaching link for CBSE science answer key for 2025 - https://school.careers360.com/boards/cbse/cbse-class-10-science-answer-key-2025
If you meant anything else please do tell I will provide that as well.
Thankyou!
