Given that $u_x=$ horizontal component of initial velocity of a projectile, $u_y=$ vertical component of initial velocity, $R=$ horizontal range, $T=$ time of flight and $H=$ maximum height of projectile. Now match the following two columns.

Column $I$ Column $II$
$(A)$ $u_x$ is doubled, $u_y$ is halved $(p)$ $H$ will remain unchanged
$(B)$ $u_y$ is doubled $u_x$ is halved $(q)$ $R$ will remain unchanged
$(C)$ $u_x$ and $u_y$ both are doubled $(r)$ $R$ will become four times
$(D)$ Only $u_y$ is doubled $(s)$ $H$ will become four times

A

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

B

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

C

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

D

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