Trouble · Answer 1

A. Olenna

Explanation:

Sugar melts the fastest when it is in a hot liquid. Stirring also increases the rate at which the sugar melts.

Olenna stirs the sugar while the coffee is still hot and before she has added the cold milk allowing the sugar to dissolve the fastest compared to the other methods of dissolving the sugar.
