The trajectory of a particle in projectile motion is given by $y = x - \frac{x^2}{80}$. Here, $x$ and $y$ are in meters. For this projectile motion, match the following with $g = 10 \, m/s^2$.

$Column-I$	$Column-II$
$(A)$ Angle of projection	$(p)$ $20 \, m$
$(B)$ Angle of velocity with horizontal after $4 \, s$	$(q)$ $80 \, m$
$(C)$ Maximum height	$(r)$ $45^{\circ}$
$(D)$ Horizontal range	$(s)$ $\tan^{-1}(1/2)$

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