Solution

The correct statement is: Using the keyword "extends," inheritance relationships can be defined both between classes and between interfaces.

In Java, an interface can inherit from another interface using the keyword "extends". Similarly, a class can also extend another class. However, a class implements an interface, not extends. Therefore, the statement "Using the keyword 'implements,' inheritance relationships can be defined both between classes and between interfaces" is incorrect. Also, an interface can extend multiple interfaces, so the statement "Interfaces can inherit only from one other interface" is also incorrect.
