Correct Answer: Casino

Solution : The correct choice is the third option .

A casino is specifically designed for gambling activities, offering various games like slots, poker, roulette, and more. This makes it the correct term for a place where gambling games are played.

The meanings of the other words are:

• Arena : A large, flat area used for public events like sports, concerts, or shows. It doesn't specifically refer to a place for gambling.
• Gymnasium : A building or room equipped for physical exercise and sports activities. It is typically associated with fitness and sports training, not gambling.
• Stadium : A large, often outdoor, structure with tiered seating for spectators, typically used for sports events.

Therefore, the right answer is casino .
