The correct answer is A) Two cranes on a single pedestal hoisting 60 tons. A twin crane lift refers to two cranes working together to lift a single load. This configuration allows for greater lifting capacity compared to a single crane. The key details in the question are "twin crane" and the total load of 60 tons, which indicates that two cranes are required to safely lift the 60-ton load. The other options are incorrect because B) describes a single crane lift, C) refers to four cranes (two sets of twin cranes) lifting 120 tons, and D) is a catch-all option that is not the most specific or accurate answer.
