### Action of `strcat()` Function

The `strcat()` function is used in the C programming language and it specifically serves to concatenate two strings. Here's a brief explanation of each option provided in the question:

1. **Compare two strings**: This is performed by the `strcmp()` function, not `strcat()`.
2. **Concatenate two strings**: This is the correct action of the `strcat()` function, which appends the content of the second string to the end of the first string.
3. **Find the length of the string**: The `strlen()` function is used to determine the length of a string, not `strcat()`.
4. **Copies one string to another**: The `strcpy()` function is used for copying strings, not `strcat()`.

### Final Answer
The correct answer is **"concatenate two strings."**
