## Step 1<br />This question is about the terminology used in the context of email communication. It asks for the term that describes a file that is included as part of an email message.<br />## Step 2<br />The options provided are 'attachment', 'upload', 'accessory', and 'eply'. We need to choose the term that is most commonly used in the context of email communication.<br />## Step 3<br />The term 'attachment' is the most appropriate term among the options. This is because when a file is included as part of an email message, it is referred to as an 'attachment'.<br />## Step 4<br />The other options do not fit the context of the question. 'Upload' refers to the process of sending a file from your local device to a server. 'Accessory' is a general term that does not specifically relate to email communication. 'Reply' refers to a response to an email, not a file included in an email.
