Solution

The correct option is A
2, 2-dimethyl propane

Volatility is tendency of a substance to evaporate at normal temperatures. Here 2, 2-dimethyl propane has the least surface area. Thus, van der Waals force of attraction between the molecules is less and hence, lesser amount of energy is required to move them apart. So, it is the most volatile compound among these.
