- The parent chain is a pentane with a methyl group (on the third carbon) and an amine group replacing one of the hydrogens. Thus, the name should end in "-pentanamine". 
- The longest chain that includes both the amine and methyl substituents is a five-carbon chain with the amine substituent on the first carbon and the methyl substituent on the third carbon. 
- The amine substituent is named as an N-ethyl-N-methyl substituent since it has both ethyl and methyl groups bound to the nitrogen atom. 
- Therefore, the IUPAC name of the given compound is N-ethyl-N-methyl-1-pentanamine (choice B).
