To answer this question, you need to understand the purpose of each script command and how they can be used to delay a single action.
Option A) Wait - The "Wait" command is typically used to pause the execution of a script for a specified amount of time. However, it does not directly support delaying a single action.
Option B) Timer - The "Timer" command is used to measure the elapsed time between two points in a script. It does not directly support delaying a single action.
Option C) Log Entry - The "Log Entry" command is used to create a log entry or message in a script. While it is not primarily used for delaying actions, it can be used in conjunction with other commands or conditions to introduce delays.
Option D) sleep - The "sleep" command is used to pause the execution of a script for a specified amount of time. It can be used to introduce delays and is commonly used in scripting languages.
Based on the given options, Option C) Log Entry does not directly support delaying a single action. Therefore, the correct answer is Option D) sleep, as it supports delaying a single action by pausing the script execution for a specified amount of time.
