C Correct answer
Explanation

Using the work formula M1*D1 = M2*D2. 6 * 18 = M2 * 3. 108 = 3 * M2. M2 = 36.

AI explanation

Using the formula for Time and Work, M1 x D1 = M2 x D2, we have 6 workers finishing the job in 18 days. Substituting the new target of 3 days for D2 gives 6 x 18 = M2 x 3. Solving for M2 results in M2 = 108 / 3 = 36 workers.
