With what cards can you get blackjack?

Blackjack is a specific hand in the game, which consists of an Ace and any card valued at ten points. The Aces can count as either one or eleven, but for the context of blackjack, when paired with a ten-value card (which includes a 10, Jack, Queen, or King), it constitutes a winning hand. This is the most optimal hand one can achieve in blackjack, as it usually pays out at a higher rate than regular wins.

The combination of any ten-value card with an Ace is the standard rule for achieving a blackjack, making option A the correct choice. Other options provided do not represent valid combinations for a blackjack; for instance, two Face cards would not result in a blackjack, though they do yield a total of twenty. Similarly, a pair of Aces or any card with a Joker does not create a blackjack. In fact, the Joker is not utilized in standard blackjack games.
