What is the default value of a boolean array element in Java if it's not explicitly initialized?

The correct answer is Option B: FALSE.

In Java, the default value of a boolean array element is FALSE if it's not explicitly initialized.

Here's the breakdown:

Option A: TRUE - This is not the default value for a boolean array element in Java. The correct default value is FALSE.

Option B: FALSE - This is the correct default value for a boolean array element in Java if it's not explicitly initialized.

Option C: 0 - This is not the default value for a boolean array element. It may be a default value for some numeric types, but not for boolean.

Option D: Null - Null is not a valid default value for a boolean array element in Java. The default value is FALSE.

So, the default value of a boolean array element in Java, if it's not explicitly initialized, is FALSE.
