What is the correct IUPAC name for the organic compound shown in the figure?

Step-by-step solution

The longest carbon chain containing the double bond has 6 carbon atoms, making the parent chain a hexene. Numbering the chain from left to right gives the double bond at position 3 and substituents at positions 2 and 4 (a methyl group at C2 and an ethyl group at C4). The locant set is (2, 4). Numbering from right to left gives the double bond at position 3 and substituents at positions 3 and 5 (an ethyl group at C3 and a methyl group at C5). The locant set is (3, 5). According to the lowest locant rule, the set (2,
