Match the ranges of the functions given in List - A with those of the items given in List-B List - A List - B (I) 3 \sin ^2 x+4 \cos ^2 x-2 (a) [\frac{1}{4}, 1] (II) \cos ^2 x+\sin ^4 x (b) [-\frac{1}{4}, \frac{1}{4}] (III) \sin ^6 {\x}+\cos ^6 {\x} (c) [1,2] (IV) \cos x \cos (\frac{2 \pi}{3}+x) \cos (\frac{2 \pi}{3}-x) (d) [\frac{3}{4}, 1] (e) [0,1]

Correct Answer is : (1) → (c) (II) → (d) (III) → (a) (IV) → (b)

(1) \to (c) ( II) \to (a) (III) \to (d) (IV ) \to (b)

(1) \to (c) (II) \to (d) (III) \to (a) (IV) \to (b)

(1) \to (b) ( II ) \to (d) (III) \to (a) (IV) \to (e)

(1) \to (b) (I) ) \to (e) (III) \to (d) (IV) \to (c)
