B Correct answer
Explanation

Ram's efficiency = 4 × Shyam's. If Shyam does x work/day, Ram does 4x work/day. Together: 5x work/day. Work completed in 11 days: 11(5x) = 55x = total work. Shyam alone: 55x/x = 55 days. If Ram worked alone: 55x/(4x) = 13.75 days. 44 days would be if Ram was 5 times efficient, 33 days if equal efficiency.
