All face cards from a pack of $52$ playing cards are removed. From the remaining $40$ cards,two are drawn randomly without replacement. The probability of drawing a pair (cards of the same denomination) is:

  • A
    $\frac{1}{13}$
  • B
    $\frac{1}{78}$
  • C
    $\frac{2}{39}$
  • D
    $\frac{4}{13}$
