Final answer:
In various communication channels, email is true for conveying complex information as it allows detailed messaging with a written record, but is not best for urgent messages and remains a professional tool when used correctly.
Step-by-step explanation:
In the context of various communication channels, the statement that is true of email is that it is ideal for conveying complex information (Option c). Email allows for detailed and structured messages that can include attachments and documentation to support complex discussions. Unlike face-to-face communication, email does not allow for immediate feedback through tone of voice or facial expressions, which can be essential for conveying urgent messages. Instead, email provides a written record of communication, enabling both sender and recipients to refer back to the details of the conversation. It is a professional communication tool widely used in business and academic settings; senders should always consider how an email might be perceived by its readers, including unintended recipients, recognizing that the content reflects on the sender's professionalism.
Email is not necessarily the best choice for urgent messages, as it may not be checked immediately by the recipient, and therefore option a) is not correct. It most certainly provides a written record, making option b) incorrect. Email remains a professional means of communication when used appropriately, which means that option d) is also not correct. When using email, it's essential to follow netiquette, compose clear and professional messages, and consider whether email is the most effective channel based on the message's complexity and urgency.
