Answer

The structure is $E$.

Work Step by Step

On the first carbon, the $CH_3$ substituent has the higher priority, and on the second carbon the $Cl$ substituent has the higher priority due to its higher molecular weight. The higher priority substituents are in the opposite directions, so the structure is $E$.
