Solution

The correct option is C

According to the IUPAC rules of nomenclature the longest chain should be considered as the main chain. Also, if more than one branch is present, as per rule, numbering should be done either from left to right or right to left so as to get the lowest number for the branch coming first in the longest chain. Hence, the structure given below is correctly representing the numbering of carbon atoms:
