Answer:

Option I.

Explanation:

(I) Option (I). is true. If a class accepts different argument type and the argument type provided is different then it will throw a error. The argument type provided and the argument expecting has to match for the compilation of the program without an error. So, option (I) is true.

(II) Option (II). is false. If the method doesn't return any value then the method declaration contains [tex]void[/tex] as the return type.

(III) Option (III) is false. The method random() returns a double value with the number between 0.0 and 1.0 with 0.0 included in the range but 1.0 is not included in the range. The method returns value with positive side but not the negative side.
