Match Column-$I$ with Column-$II$.

Column-$I$	Column-$II$
$(1)$ Vertical component of velocity is zero	$(a)$ Tangent to the parabolic path
$(2)$ Linear velocity	$(b)$ Maximum height point of the projectile trajectory

(A) At the maximum height of a projectile's trajectory,the vertical component of velocity $(v_y)$ becomes zero. Thus,$(1)$ matches with $(b)$.
The linear velocity vector at any point on the trajectory is always directed tangent to the parabolic path. Thus,$(2)$ matches with $(a)$.
Therefore,the correct matching is $(1-b, 2-a)$.
