Understanding "Advantage" in Lawn Tennis
In lawn tennis, the term "advantage" is a crucial part of the scoring system, especially during deuce situations. Here’s a detailed explanation:

What is Advantage?
- In tennis, when the score reaches 40-40, it is referred to as "deuce."
- From deuce, a player must win two consecutive points to win the game.

How Advantage Works:
- The first player to win a point after deuce is said to have "advantage."
- If the player with the advantage wins the next point, they win the game.
- If they lose the next point, the score goes back to deuce.

Importance of Advantage:
- The advantage system adds excitement and intensity to the game, as players must maintain focus and composure.
- It makes each point in a deuce situation critical, as the momentum can shift quickly.

Comparison to Other Sports:
- Unlike sports like badminton, cricket, or hockey, where the term "advantage" is used differently, tennis has a distinct scoring method that incorporates this term into its gameplay.
- In badminton, the scoring is straightforward, and in cricket, "advantage" refers more to the status of the game rather than a specific point in scoring.

Conclusion:
- Therefore, in the context of the question, the correct answer is indeed option 'B' (Lawn Tennis), as "advantage" is an integral part of its scoring system, making it unique among the listed sports.
