C Correct answer
Explanation

Using the work formula: M1D1 = M2D2, where M is number of workers and D is days. Initially: 76 × 33 = M2 × 44. Solving: M2 = (76 × 33) / 44 = 76 × (33/44) = 76 × (3/4) = 57 ladies actually worked. Therefore, ladies who did not report = 76 - 57 = 19. The inverse relationship between workers and time is key here.
