Given : A circle, 2x2 + 2y2 = 5 and a parabola, y2 = 4 underroot(5) x. Statement − I : An equation of a common tangent to these curves is y = x +underroot(5) .

Statement − II : If the line, y= mx +underroot(5)/m = + (m not equals to zero 0) is their common tangent, then m satisfies m4 − 3m2 + 2 = 0.

(1) Statement - I is True; Statement -II is true; Statement-II is not a correct explanation for Statement-I

(2) Statement -I is True; Statement -II is False.

(3) Statement -I is False; Statement -II is True

(4) Statement -I is True; Statement -II is True; Statement-II is a correct explanation for Statement-I
