C Correct answer
Explanation

The total work is constant, so 76 × 33 = n × 44, giving n = 57 ladies who worked. Hence 76 - 57 = 19 ladies did not report, so option C is correct.

AI explanation

Using the inverse proportionality method (M1 times D1 equals M2 times D2), the initial workforce times 33 days equals the final workforce times 44 days. We calculate the final number of ladies as 76 multiplied by 33 divided by 44, which equals 57 ladies. The number of ladies who did not report is 76 minus 57, which equals 19.
