(1) Consider a circle x²+y²-8x-18y+93=0. Which center 'C' and point (2, 5) is outside the circle from the point P, a pair of tangents PO and PR are drawn to the circle with S as the midpoint of QR. The line joining P to C intersects the given circle at A and B. Which of the following holds good:

(a) CP is AM of AP and BP

(b)PR is GM of PS and PC

(c) PS is HM of PA and PB

(d) The angle between the 2 tangents from P is tan^-1(3/4)
