(a) Statement 1 and Statement 2 are correct. Statement 2 is the correct explanation for the Statement 1 (b) Statement 1 and Statement 2 are correct. Statement 2 is not the correct explanation for the Statement 1 (c) Statement 1 is true but Statement 2 is false (d) Statement 2 is true but Statement 1 is false

Statement 1 : The number of common tangents to the circles x^(2) + y^(2) =4 and x^(2) + y^(2) -6x - 6y = 24 is 3. Statement 2 : If two circles touch each other externally thenit has two direct common tangents and one indirect common tangent.

STATEMENT-1 : Let x^(2) + y^(2) = a^(2) and x^(2) + y^(2) - 6x - 8y -11 = 0 be two circles. If a = 5 then two common tangents are possible. and STATEMENT-2 : If two circles are intersecting then they have two common tangents.

STATEMENT-1 : Let x^(2) + y^(2) = a^(2) and x^(2) + y^(2) - 6x - 8y -11 = 0 be two circles. If a = 5 then two common tangents are possible. and STATEMENT-2 : If two circles are intersecting then they have two common tangents.

If the circles x^(2) +y^(2) - 6x – 8y +c = 0 and x^(2) + y^(2) =9 have three common tangent then c=
