Which of the following Grand Slam tennis tournaments is played on grass courts?

Introduction / Context:
The four Grand Slam tournaments are the most prestigious events in professional tennis. Each Grand Slam is played on a different type of surface, and exam questions often test whether you can correctly match the tournament with its playing surface. Grass courts are the original traditional surface for lawn tennis, and one Grand Slam in particular has preserved that tradition. This question asks you to select which Grand Slam is played on grass courts.

Given Data / Assumptions:

• We are dealing with Grand Slam tennis tournaments.
• The options given are US Open, French Open, Wimbledon, and Australian Open.
• Each of these tournaments is associated with a specific primary surface.
• We have to identify the one that is played on grass.

Concept / Approach:
The concept is surface based classification of Grand Slam events. The French Open is played on clay courts, the US Open and Australian Open are currently played on hard courts, and Wimbledon is played on natural grass courts. An effective approach is to memorise the simple mapping: French Open equals clay, Australian Open equals hard court, US Open equals hard court, and Wimbledon equals grass. Once this mapping is clear, questions on Grand Slam surfaces become very easy to answer.

Step-by-Step Solution:
Step 1: List all four Grand Slams and recall their surfaces. Step 2: French Open is played on clay courts. Step 3: US Open is played on hard courts. Step 4: Australian Open is also played on hard courts. Step 5: Wimbledon is the only Grand Slam played on grass courts, so choose Wimbledon.

Verification / Alternative check:
You can verify by picturing famous matches and the court colour. At Wimbledon, you see green grass, white clothing, and a traditional setting. The French Open is known for red clay at Roland Garros. The US Open has a blue hard court surface in recent decades, and the Australian Open is also associated with blue or green hard courts. These visual cues strongly confirm that Wimbledon is the one played on grass.

Why Other Options Are Wrong:
US Open: This tournament is played on hard courts and is known for its fast surface and night matches, not for grass courts.
French Open: This is the only Grand Slam played on clay courts, making it the clay specialist event, not a grass court tournament.
Australian Open: This event is played on hard courts and is not associated with grass courts in the modern era.

Common Pitfalls:
Sometimes learners confuse past historical changes with current surfaces, since a few tournaments used different surfaces many decades ago. Others simply misremember which of the hard court tournaments is which. The safest strategy is to memorise the modern mapping: clay for French Open, grass for Wimbledon, and hard courts for both Australian Open and US Open. Repeating this mapping regularly will help you avoid confusion during exams.

Final Answer:
The Grand Slam tennis tournament played on grass courts is Wimbledon, so option C is correct.
