In the reaction:

the product E is

(A)(see structure)
✓ Correct
(B)(see structure)
(C)(see structure)
(D)(see structure)

Answer: (A)

Solution

This is a Wurtz-Fittig coupling: an aryl halide treated with sodium joins its two aromatic units through the carbons that carried the halogen. Here two tolyl fragments are stitched together, producing a dimethylbiphenyl. The product

E

is the biphenyl in which the two rings are bonded directly and each still bears its methyl group.
