Final Answer :
C
Explanation :
- The longest continuous carbon chain is 8 carbons, so the root name should be octane.
- There are two amides, which are named as substituents attached to the parent chain with the -amide suffix. The two amides are located on carbons 5 and N, so the substituent names are 5-methyl and N-methyl.
- The remaining substituent is an ethyl group attached to carbon 2.
Putting all the pieces together, the correct systematic name is 5,N-dimethyl-2-ethyloctanamide.
