Answer: Option C

$$\begin{array}{rl}& \text{According to the question,}\\ & \text{1 man}=\text{2 women}=\text{3 boys}\\ & \text{1 man}=\text{2 women}\\ & \text{1 man}=\text{3 boys}\\ & \frac{1}{2}\text{ man}=1\text{ women}\\ & \frac{1}{3}\text{ man}=\text{1 boys}\\ & =\text{1 man}=1\text{ woman}=1\text{ boys}\\ & =\text{1 man}=\frac{1}{2}\text{man}=\frac{1}{3}\text{ man}\\ & =\frac{11}{6}\text{ man}\end{array}$$
1 man can complete a work in 88 days
$$\begin{array}{rl}& \frac{11}{6}\text{man can complete a work in}\\ & =\frac{88}{\frac{11}{6}}=48\text{ days }\end{array}$$
