The double bond is between the second and fourth carbon atoms. Therefore, the correct IUPAC name is 3-ethyl-2,4-dimethyl-2-pentene (B). Option A has the correct number of methyl groups, but the ethyl group is located incorrectly. Option C has the correct number of methyl groups, but the ethyl group is missing. Option D has the correct location of the ethyl group, but the positions of the methyl groups are incorrect.
