D Correct answer
Explanation

First, calculate the productivity rate: 2 persons x 2 hours x 2 days = 8 person-hours for 2 machines, meaning 4 person-hours per machine. For the new scenario: 6 persons x 6 hours x 6 days = 216 person-hours. Dividing 216 by 4 person-hours per machine gives 54 machines.
