Solution
The statement that is FALSE about abstract classes in Java is: "A class can inherit from multiple abstract classes."
In Java, a class cannot inherit from multiple abstract classes due to the single inheritance feature of Java. Java does not support multiple inheritance with classes. Although, it can be achieved with interfaces.
