Which of the following are example of B2C?AOnline shopping websitesBKey heavy industriesCPurchase by a wholesaler from manufacturerDNone of the above

To determine which of the options are examples of B2C (Business-to-Consumer), we need to understand the concept of B2C. B2C refers to transactions or interactions that occur between a business and individual consumers.

Let's analyze each option:

A) Online shopping websites: This option is an example of B2C because online shopping websites allow individual consumers to purchase products or services directly from businesses.

B) Key heavy industries: This option does not fall under B2C. Key heavy industries typically involve large-scale manufacturing or production processes and do not directly interact with individual consumers.

C) Purchase by a wholesaler from manufacturer: This option does not fall under B2C either. It describes a transaction between a wholesaler (business) and a manufacturer (another business), not involving individual consumers.

D) None of the above: This option is incorrect because option A, online shopping websites, is an example of B2C.

Therefore, the correct answer is A) Online shopping websites.
