Which of the following reacts with methylmagnesium iodide to produce tert-butyl alcohol?

Given below are two statements:
Statement $I:$ The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole-dipole interactions.
Statement $II:$ The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of $H$-bonding.
In the light of the above statements,choose the most appropriate answer from the options given below:
