$C_6H_{13}OH\rightarrow C_6H_{12}$
Mole weight of $C_6H_{13}OH=102$
Mole weight of $C_6H_{12}=84$
$102g$ cyclohexanol =$84gC_6H_{12}$
$\therefore$ 100g cyclohexanol =$\large\frac{84\times 100g}{102}$$C_6H_{12}$
Also $\%$ yield is 75%
Weight of $C_6H_{12}=\large\frac{84\times 100\times 75}{100\times 102}$
$\Rightarrow 61.764$
Hence (a) is the correct answer.
