Two particles are projected from a tower in opposite directions horizontally with speed $10\,m/s$ each. At $t=1\,s$,match the following two columns.

Column $I$	Column $II$
$(A)$ Relative acceleration between two	$(p)$ $0$ $SI$ unit
$(B)$ Relative velocity between two	$(q)$ $5$ $SI$ unit
$(C)$ Horizontal distance between two	$(r)$ $10$ $SI$ unit
$(D)$ Vertical distance between two	$(s)$ $20$ $SI$ unit

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