Penny always hits "reply to all" whenever she answers a team email, even if the email was a question posed by one other person and directed only to Penny. When she initiates an email about her project, she sends it to everyone in her department. Judging only from this information, what impact is Penny most likely having on her department's communications? She is spreading confidential information to unauthorized people. She is making everyone in her department feel included as part of the team. She is helping make the department work more efficiently. She is ensuring that each person on the team clearly knows their assignments. She is contributing to email overload in her department.

# Brief Explanations:<br />Penny's habitual use of the "reply to all" function and tendency to send project-related emails to everyone, regardless of their relevance to the discussion or project, is likely leading to a lot of unnecessary emails crowding inboxes. This can contribute to email overload, where too many emails reduce efficiency by causing distractions, burying important emails, and generally demanding more time for sorting and reading from the staff. Therefore, the issue might not necessarily be about confidentiality, inclusivity, or clarity of assignments, but more about the volume of emails being sent and received.<br /># Answer: <br />She is contributing to email overload in her department.
