Answer: (C)

Verified step by step guidance

1. Identify the parent chain: The name '4-tert-butyl-3-isopropyl-2-methyloctane' indicates that the parent chain is 'octane', which consists of 8 carbon atoms in a continuous chain.
2. Number the carbon atoms in the parent chain: Start numbering from the end of the chain that gives the substituents the lowest possible numbers. In this case, start from the left to right.
3. Locate and attach the substituents: According to the name, a tert-butyl group is attached to carbon 4, an isopropyl group is attached to carbon 3, and a methyl group is attached to carbon 2.
4. Draw the structure: Begin by drawing the 8-carbon parent chain. Then, add the tert-butyl group (a carbon bonded to three methyl groups) to carbon 4, the isopropyl group (a carbon bonded to two methyl groups) to carbon 3, and the methyl group (a single carbon) to carbon 2.
5. Verify the structure: Ensure that all carbon atoms have four bonds and that the substituents are correctly placed according to the IUPAC name.
