The answer is the first one (or A): Only the period (.) is a prohibited character in file names created on the macOS.

Explanation for each option:

a. Only the period (.) is a prohibited character in file names created on the macOS.

• This statement is incorrect. While the period (.) is not prohibited in macOS file names, there are other characters that are prohibited or reserved, such as the colon (:). Therefore, this option is not true.

b. You can save a file with a new name to keep track of document versions.

• This statement is true. Saving a file with a new name is a common practice to keep track of different versions of a document.

c. A file name should identify the content and purpose of the file.

• This statement is true. A descriptive file name helps users understand the content and purpose of the file at a glance.

d. Files you work on using a web app save changes as you make them.

• This statement is true for many modern web applications, such as Google Docs, which automatically save changes in real-time.

Summary: Option A is not true because the period (.) is not the only prohibited character in macOS file names; other characters like the colon (:) are also prohibited. The other options (B, C, and D) are true statements about managing file names and file placement.
