The correct answer is indeed D. Here is why:
1. We first identify the longest continuous carbon chain. This happens to be the carbons CH3(C)CH3 if you're looking at the diagram.
2. The substituent thus happens to be the other CH3(methyl) attached to the second carbon atom. Thus, 2-methyl.
3. Finally, the functional group is the alkanol(-OH) group, and since the longest continuous carbon chain is three carbon atoms long, it is propanol. The alkanol group is specifically attached to the second carbon, making it propan-2-ol.
Thus, the name is 2-methylpropan-2-ol.
Thank you and God bless you. Remember, Jesus loves you.
