Tangents are drawn from the point `P(1,-1)` to the circle `x^2+y^2-4x-6y-3=0` with centre C, A and B are the points of contact. Which of the following are correct?

Tangents are drawn from the point (-1,2) to the parabola y^(2)=4x The area of the triangle for tangents and their chord of contact is

Tangents drawn from the point P(1,8) to the circle x^(2) + y^(2) - 6x - 4y -11=0 touch the circle at the points A and B. The equation of the circumcircle of the triangle PAB is:

Two tangents are drawn from the point P(-1,1) to the circle x^(2)+y^(2)-2x-6y+6=0 . If these tangen tstouch the circle at points A and B, and if D is a point on the circle such that length of the segments AB and AD are equal, then the area of the triangle ABD is equal to
