Before checking the answer key, ask yourself these two questions for every MCQ:
✅ Why is the correct option right?
✅ Why are the other three options wrong?
If you can explain both, your concept is truly clear. If not, revise the related NCERT concept and try again.
Remember: Real learning happens when you understand the reason, not when you memorize the answer. 

Answer Key: 

Q1-b | Q2-b | Q3-d | Q4-b | Q5-b | Q6-b | Q7-a | Q8-c | Q9-b | Q10-c
