According to the IUPAC nomenclature, the longest continuous carbon chain should be selected as the parent chain. Here, the parent chain is a four-carbon chain, and there is a diethyl group at the second carbon. The remaining two carbons are attached to each other and to the second carbon through a single bond. The compound is, therefore, named as sec-butyldiethylamine.

Note: The other options either have incorrect prefixes or incorrectly indicate the positions of the substituents.
