Solution

PayTM is a digital payment platform that allows users to make transactions like bill payments, mobile recharges, and money transfers. It is primarily used as a mobile wallet and financial services app, not for social media purposes.

The other options are all popular social media platforms:

• Facebook: A social media network for connecting with friends, sharing updates, and more.
• Twitter: A microblogging platform for sharing short messages, updates, and news.
• Instagram: A photo and video-sharing social network owned by Meta (Facebook).

Therefore, PayTM is not a social media platform.
