Given the following interfaces: public interface Inter1 { public abstract void m10; public abstract void m20; } public interface Inter2 extends Inter1{ public abstract void m30; } public interface Inter3 extends Inter1{ public abstract void m40; } If you are asked to define a concrete class called Main that implements Inter3, what are the methods that have to be overridden: (1 Point) m1 m2 mi m2 m3 m1 m2, m4
