hi,
ans C.. 95
at any point between the two parallel lines, the angle formed by the two points at the center will be equal to the sum of angle made by these lines with parallel lines(a,c in this case).. a+c=40+55=95..
for explanation of above point ,refer to the solution below
refer the attached drawing when the two points on the parallel lines are joined..
in the drawing a+x+c+y= 180(consecutive interior angles are 180 between two parallel lines)..
or 40+x+55+y=180.. x+y=85...
in the triangle formed by angles x,y and b, x+y+b=180..
or 85+b=180....
so b=95

I also go with C.
Since the lines are parallel we get the following shape (i am sorry that it looks so ugly...).
