AUse event queues to broadcast state changes asynchronously to all clients

BStore all states in a single global variable accessed by all threads

CUse blocking calls to update states synchronously for each player

DSend state changes only when the game ends

Step-by-Step Solution

Solution:

Step 1: Understand event-driven architecture benefits
It decouples components and allows asynchronous communication, improving scalability.
Step 2: Apply to game state management
Using event queues to broadcast state changes lets multiple clients update independently and efficiently.
Final Answer:
Use event queues to broadcast state changes asynchronously to all clients -> Option A
Quick Check:
Event-driven + state = async broadcast [OK]

Quick Trick: Broadcast state changes asynchronously for scalability [OK]
