P

and

Q

are the points of intersection of the circles

x^2+y^2+3 x+7 y+2 p-5=0

and

x^2+y^2+2 x+2 y-p^2=0

, then there is a circle passing through

P, Q

and

(1,1)

for

View answer and explanation

Correct option: A

all values of

p

Option A (all values of

p

) is correct because the equation of the circle passing through the intersection points P and Q exists for all values of p.
