Final answer:
A web portal is a website that offers a variety of Internet services from a single, convenient location.So the correct option is 1.
Step-by-step explanation:
Search engines focus on finding information across the web, not providing a variety of services from a single location.
Social media platforms primarily cater to social interaction and networking, not diverse internet services.
E-commerce websites are designed for buying and selling goods online, not offering a broad range of services.
Web portals aggregate various services like news, email, forums, shopping, etc., into a single unified platform.
Therefore, option 1 accurately describes the definition of a web portal.
So the correct option is 1.
