Final answer:
To describe one's proficiency with MS Office, various levels can be chosen, with advanced users usually updating to the latest version for compatibility reasons.
Step-by-step explanation:
When describing the level of comfort with MS Office, one might choose from several options. If you have advanced skills and regularly update to the latest version of MS Office, it would be accurate to select, "I have advanced skills in using MS Office and regularly update to the latest version." It's important to keep MS Office up to date, as files created with newer versions may not be compatible with older software. This potential issue is a result of software programs being upwardly compatible only, which requires users to upgrade to maintain compatibility with files shared by colleagues or friends.
