We have to use the following theorem

An Angle formed by a chord and a tangent that intersect on a circle is half the measure of the intercepted arc .

And it is given that arc m BC = 89 degree.

[tex] \angle BCP = \frac{1}{2}( m BC) [/tex]

[tex] \angle BCP = \frac{1}{2}( 89)=44.5 [/tex]

Correct option is A.
