Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. EC

Difference of percentage of Boys and Girls:

CE: [(3 – 2)/5] × 100 = 20%

CS: [(5 – 4)/9] × 100 = 11.11%

IT: [(4 – 3)/7] × 100 = 14.28%

ME: [(6 – 5)/11] × 100 = 9.09%

EC: [(10 – 9)/19] × 100 = 5.26%

Hence, in EC, the difference is minimum.
