Concept:IUPAC names are based on the longest continuous carbon chain and alphabetical order of substituents.
Explanation:The longest carbon chain contains four carbon atoms, so the parent name is butane.
The bromine atom gives the bromo substituent, and there is also a methyl group attached to the chain.
Both substituents are located on the second carbon atom of the chain.
Alphabetically, bromo comes before methyl.
Therefore, the correct IUPAC name is 2-bromo-2-methylbutane.
Answer:The correct option is C: 2-bromo, 2-methyl butane.
