Answer:
The correct option is A
That is 2,4,5-Trimethyl-4-propylheptane
Explanation:
Looking at the structure the longest carbon chain is 7 as shown on the second uploaded image
Also from the diagram of the structure we can identify that is longest chain has 3 methyl group attachment and one propyl group attachment
Now going through this longest chain the numbering of this attachment them the lowest number is the correct way so as we can see
2,4,5-Trimethyl-4-propylheptane gives the lowest numbering compared to 3,4,6-Trimethyl-4-propylheptane so the correct IUPAC names is 2,4,5-Trimethyl-4-propylheptane
