If $$|\vec{A}|=2$$ and $$|\vec{B}|=4$$, then match the relations in column-I with the angle $$\theta$$ between $$\vec{A}$$ and $$\vec{B}$$ in column-II.

 Column-I Column-II (a) $$\vec{A}.\vec{B}=0$$ (i) $$\theta=0^{\circ}$$ (b) $$\vec{A}.\vec{B}=8$$ (ii) $$\theta=90^{\circ}$$ (c) $$\vec{A}.\vec{B}=4$$ (iii) $$\theta=180^{\circ}$$ (d) $$\vec{A}.\vec{B}=-8$$ (iv) $$\theta=60^{\circ}$$


Choose the correct answer from the options given below:

 1 (a)–(iii), (b)-(ii), (c)-(i), (d)-(iv) 2 (a)–(ii), (b)-(i), (c)-(iv), (d)-(iii) 3 (a)–(ii), (b)-(iv), (c)-(iii), (d)-(i) 4 (a)–(iii), (b)-(i), (c)-(ii), (d)-(iv)
