Answer :

The question asks which option is not a web portal. To address this, let's first define what a web portal is.

A web portal is a specially designed website that brings information from diverse sources, like emails, online forums, and search engines, together in a uniform way. Generally, each information source gets its dedicated area on the page for displaying information. Portals provide a way to access various applications and services.

Now, let's examine each option:

  1. CRM Portal: CRM stands for Customer Relationship Management. A CRM portal typically provides access to a CRM system through a web interface, allowing users to manage customer relationships, track sales leads, and access customer data.

  2. HR Portal: HR (Human Resources) portals are web interfaces that provide various HR-related functions, such as payroll, benefits management, and employee self-service options. They allow employees and HR professionals to manage important HR tasks and information.

  3. Sales Portal: A sales portal provides a centralized online platform for sales teams to access resources, like product information, sales tools, and client data, to facilitate effective sales activity.

  4. None of the above: This option implies that all the mentioned options are web portals.

Considering the definitions, each of the given options (CRM portal, HR portal, and Sales portal) qualifies as a web portal because they all provide a web-based interface for users to access specific services and information related to their respective fields.

Therefore, the correct answer is d. None of the above, as all listed options are indeed web portals.
