Solution

The correct option is D 2,2,6,6,7-Pentamethyloctane
The correct IUPAC name is 2, 2, 6, 6, 7-Pentamethyloctane.

While numbering, the longest continuous carbon chain will get the highest priority. If more than one substituent is present, the chain is numbered from direction that will result in lowest possible number in the name of compound.
