Here's the answer.

Bearing of given line=FB of previous line+Included angle.
Then add or deduct 180.
So,
75 + 90(FB of pvs line) + 90(included angle) - 180 = 75.

Bearing 34-5.
= 29 because rectangular ABCD 29 * 2 = 58 + 17 = 75.

Thanks @Lalit.

This is the case of the rectangle so each BB of each corner would be the same as given 75 (Answer A is correct).

Rectangular ABCD.
Bearing of line AB = Bearing of line DC.
75°=75°.

AB 75°.
BC 75+90.
CD 75+90+90.
DC ..CD-180 =75°.

It's rectangular so back bearing of every point will be 255(75+180) and bearings will be 255-180 which is 75.
