A Correct answer
Explanation

Work rates: A completes in 12 days, so rate = 1/12. B completes half work in twice A's time (24 days), rate = 1/48. C completes one-fourth work in 1.5× A's time (18 days), rate = 1/72. Total rate = 1/12 + 1/48 + 1/72 = 17/144. A's wage share = (1/12)/(17/144) = 12/17 = 70.6%, which rounds to approximately 70%.
