$C{H}_{3}C{H}_{2}C{H}_{2}Cl+C{H}_3\underset{\underset{Cl}{|}}{C}HC{H}_3\underset{Dryether}{\overset{Na}{\to }}\text{Products}$

Which of the following is not a product of above reaction? 

The products are due to coupling of different alkyl groups.$C{H}_{3}C{H}_{2}C{H}_{2}Cl$ is $RCl$ and $C{H}_3\underset{\underset{Cl}{|}}{C}HC{H}_3$ is $R\text{'}Cl,$ the products will be RR,R’R’ and RR’.
