Final answer:
The correct answer is option (a) to communicate with many people at the same time.
Step-by-step explanation:
Emails are used to communicate with many people, share documents, and files, and keep a record of communication. Email is a convenient and efficient way to send messages to multiple recipients simultaneously. By composing one email and adding multiple recipients, you can save time and effort compared to individually addressing each person.
Option (b) to share documents and files is another reason for using emails. You can attach files such as documents, presentations, or images to an email and send them to others. This allows for easy and quick sharing of information between individuals or groups.
Option (c) to talk to each other in real-time is not typically associated with emails. Real-time communication is more commonly done through instant messaging platforms like chat or video calls. However, it is possible to have a near real-time conversation through emails if both parties are actively checking and responding to messages.
Lastly, option (d) to keep a record of communication is a significant advantage of using emails. When you send an email, a copy is saved in your sent folder, providing you with a record of what was sent, when it was sent, and who it was sent to. This can be helpful for reference or accountability purposes.
