The longest carbon chain contains 10 carbons. We start numbering from the end where the substituents are located. The methyl substituent is located at carbon 7, the ethyl substituent is at carbon 4 and the propyl substituent is at carbon 5. Therefore, the correct name is 4-ethyl-7-methyl-5-propyldecane. All the other options have incorrect placement or number of substituents.
