Which of the following is not an advantage of e-mail?

Choosing "More of an interruption than a phone call" as the correct answer aligns with understanding the nature of e-mail communication. E-mail provides a platform for individuals to send messages without needing immediate feedback or interruption in the ongoing activities of the recipient. This characteristic makes e-mail a less intrusive form of communication compared to phone calls, which often require the recipient's immediate attention and can disrupt their workflow.

In contrast, advantages such as instant communication allow for messages to be sent and received rapidly, and documentability highlights the ability to keep a record of communications for future reference. E-mails serve as a written record, making it easier to track conversations and decisions, which can be beneficial in a professional setting. Therefore, the belief that e-mail can be more of an interruption contrasts with its intended design, which is to facilitate communication while reducing disruptions.
