Which of the following describes e‐commerce?

Answer: Option A

Correct Answer: A - Doing business electronically
This option accurately captures the essence of e-commerce. It encompasses all aspects, including online transactions, digital marketing, online customer service, and other digital interactions related to business operations.

Why other options are incorrect:
Option B - Doing business: This is too broad. Traditional, offline business is also "doing business," but it's not e-commerce.
Option C - Sale of goods: While a significant part of e-commerce, it's not the whole picture. E-commerce involves much more than just sales; it includes services, digital downloads, and various other transactions.
Option D - All of the above: Because options B and C are not fully encompassing definitions of e-commerce, this option is also incorrect.
