Assertion: Most probable velocity is the velocity possessed by maximum fraction of molecules at the same temperature.
Reason: On collision, more and more molecules acquire higher speed at the same temperature.

Options

A. If both (`A`) and (`R`) are correct and (`R`) is the correct explanation of (`A`).
B. If both (`A`) and (`R`) are correct, but (`R`) is not the correct explanation of (`A`).
C. If (`A`) is correct, but (`R`) is incorrect.
D. If (`A`) is incorrect, but (`R`) is correct.
