Concept:The most used messaging app is identified by the number of monthly active users worldwide.
Explanation:WhatsApp is the correct answer because it is the leading messaging app globally.
WhatsApp has over
2 billion active users, which is the highest among all messaging apps.
The app is available in more than
180 countries across the world.
It processes over
100 billion messages every day, showing very high user engagement.
WhatsApp offers free messaging and calling, making it accessible to a massive audience.
It also provides end-to-end encryption, ensuring that only the sender and receiver can read the messages.
WhatsApp Business allows small businesses to connect directly with customers.
In comparison, Facebook Messenger has about
1 billion users, WeChat has about
1.3 billion users, Telegram has around
900 million users, and Snapchat has fewer than
800 million users.
Therefore, no other app matches WhatsApp's user base, making it the most used messaging app globally.
