Question 8

The value of a is Undefined.

In JavaScript, when a variable is declared but not initialized, its value is automatically set to undefined. Therefore, the value of the variable `a` in the provided code is undefined.

A) FALSE

This option is incorrect because the value of `a` is not a boolean false. In JavaScript, a variable must be explicitly assigned a value of false for it to hold that value, which is not the case here.

B) TRUE

This option is also incorrect. Similar to the previous option, the variable `a` has not been assigned any value, including the boolean value true. Therefore, it cannot be true.

C) Undefined

This option is correct. In JavaScript, if a variable is declared but not assigned a value, it is automatically set to undefined, which accurately reflects the state of variable `a` in the given code.

D) Null

This option is incorrect as well. Null is an intentional absence of any object value, and for `a` to be null, it would have to be explicitly set to null. Since `a` has not been initialized, it is not null but rather undefined.

Conclusion

The correct answer is undefined because it aligns with JavaScript's behavior of assigning the value undefined to variables that are declared but not initialized. All other options—FALSE, TRUE, and Null—do not apply since they require explicit assignments that are not present in the provided code context.
