Answer

Correct option: A.

$\mathrm{CH}_3 \mathrm{I}<\mathrm{C}_2 \mathrm{H}_5 \mathrm{I}<\mathrm{C}_3 \mathrm{H}_7 \mathrm{I}$

Haloalkanes are more dense than alkane, from which they are derived and usually more dense than water. Density increases with the number of carbon and halogen atom increases.
