The Correct Option is A
Solution and Explanation
Step 1: Concept
The mode is the value that appears most frequently in a data set.
Step 2: Meaning
Look at the "No. of boys" (frequency) row to find the highest number.
Step 3: Analysis
The frequencies are 12, 9, 8, 6, 6, 5, 4, 3. The maximum frequency is 12.
Step 4: Conclusion
The age corresponding to the frequency 12 is 10. Therefore, the modal age is 10. Final Answer: (A)
