D Correct answer
Explanation

If Ram is 4 times as efficient as Shyam, then Ram does 4 units of work per day while Shyam does 1 unit per day. Together, they do 5 units per day and complete the work in 11 days, so total work = 5 × 11 = 55 units. Shyam alone would take 55 units ÷ 1 unit/day = 55 days. This is option D.
