Homework Statement

The Attempt at a Solution


The answer is supposed to be D but I can't figure out why, my method gave me B
counting the number of points in the longest chain there are 7 and there are only single bonds so without the branches I have heptane. there is a ethyl attached to the second point and a methyl attached to the fourth and fifth point so it should be 2-ethyl-4,5-dimethylheptane
