Answer:

105 is right

Step-by-step explanation:

Given that AB=BC

Also angle BDC =37.5

Then angle subtended at the centre would be twice angle subtended at the arc

Hence we get

Angle CBD = supplementary of twice 37.5

In other words CBD and 75 degrees are supplementary

Hence Angle CBD = 180-75

=105 degrees

Last option is right.
