The correct answer is: In Java, a variable must be declared with a specific data type, such as int, char, or String, and then initialized with a value. The declaration and initialization of a variable in Java is done using the following syntax:dataType variableName = value;In the given options, only the third option, , follows the correct syntax for declaring and initializing a variable in Java. The variable "myNumber" is declared as an integer (int) and initialized with the value 10.The first option, , is incorrect because it does not specify the data type for the variable "myInteger". The second option, char = 'a';, is also incorrect because it does not specify the name of the variable. The fourth option, "Variable", is not a valid declaration or initialization statement in Java.
