Answer:
Option 4 is the correct answer to the above question.
Explanation:
In the Linux operating system, The etc folder is listed on the root directory. When any user wants to go in the root directory of the Linux operating system from anywhere, then he needs to follow the command of the name of the folder where he wants to go with the '/' symbols. The above question states that the user wants to go to the etc folder of the root directory, then he needs to press the command '/etc' with the help of cd command because cd command is used to open any folder.
