Given,

angle BCD = 1/2 angle BAD

Let angle BCD = x

Then, BAD = 2x

In order to work out this on , one needs to draw an angle bisector from A to E on BC.

AECD is a parallelogram . Therefore , AD = EC = 7.

Since , BC and AD are parallel thus angle BAD = Angle BEA. Since , AB = 5, EB = 5 too.

BC = BE + EC = 5 + 7 = 12.

Thus B is the best option.
