Final answer:

The correct answer is option C. r-x. The string 'r-x' represents read and execute permissions but no write permissions.

Step-by-step explanation:

The correct answer is option C. r-x. In a symbolic representation of file permissions, the first character represents the read (r) permission, the second character represents the write (w) permission, and the third character represents the execute (x) permission. In this case, the string 'r-x' means that the file has read and execute permissions, but no write permissions.

The correct answer is option C. r-x. In Unix-like operating systems, file permissions are represented by a combination of three characters for the user who owns the file, three characters for the group that owns the file, and three characters for everyone else. Each of these sets can include the characters 'r' (read), 'w' (write), and 'x' (execute). A dash ('-') is used to represent the absence of a permission. Therefore, a file with read and execute permissions but without write permission for a user is represented as 'r-x'.
