Which of the following is true about the "use strict" mode in JavaScript?OptionsIt makes JavaScript more permissive and forgiving of errors.It allows the use of undeclared variables.It is automatically enabled in all JavaScript code.It enforces stricter parsing and error handling in JavaScript.

The correct answer is: "It enforces stricter parsing and error handling in JavaScript."

Here's why:

1. "use strict" does not make JavaScript more permissive and forgiving of errors. In fact, it does the opposite. It makes the JavaScript engine more strict and less forgiving of certain types of errors.

2. "use strict" does not allow the use of undeclared variables. Again, it does the opposite. In strict mode, any reference to a variable that has not been declared will throw an error.

3. "use strict" is not automatically enabled in all JavaScript code. It must be declared at the beginning of a script or a function to be enabled.

4. "use strict" does enforce stricter parsing and error handling in JavaScript. This is the main purpose of strict mode. It helps catch common coding mistakes and "unsafe" actions such as deleting variables, functions, or function arguments.
