A vector has a magnitude $x$. If it is rotated by an angle $\theta$, then magnitude of change in vector is $n x$. Match the following two columns.

Colum $I$	Colum $II$
$(A)$ $\theta=60^{\circ}$	$(p)$ $n=\sqrt{3}$
$(B)$ $\theta=90^{\circ}$	$(q)$ $n=1$
$(C)$ $\theta=120^{\circ}$	$(r)$ $n=\sqrt{2}$
$(D)$ $\theta=180^{\circ}$	$(s)$ $n=2$

• A
  $( A \rightarrow q , B \rightarrow r , C \rightarrow p , D \rightarrow s )$
• B
  $( A \rightarrow s , B \rightarrow r , C \rightarrow p , D \rightarrow q )$
• C
  $( A \rightarrow q , B \rightarrow p , C \rightarrow r , D \rightarrow s )$
• D
  $( A \rightarrow p , B \rightarrow r , C \rightarrow q , D \rightarrow s )$
