Formula of cyclohexanol is C6H11. OH i.e.
Molecular mass of C6H11.OH=100
Molecular mass of cyclohexane (C6H12)=84
∵ For 84g of cyclohexane, we need =100g of material C6H11.(OH)
∴ For 20g of cyclohexane, we need =

100×20

84

=23.80g of C6H11(OH)
∵54g of C6H11(OH) get from =100g of C6H11(OH)
∴23.8g of C6H11(OH) get from =

100×23.8

54

=44%
∴ Hence, (d) is the correct answer.
