Code would be like:
public abstract class ABS1

public abstract void Read();
}
public abstract class ABS2:ABS1
{
public abstract void Write();
}
public class AbsChild : ABS2
{
public override void Read()
{
throw new NotImplementedException();
}

        public override void Write()
        {
            throw new NotImplementedException();
        }
    }

yes, we can inherit an abstract class from another abstract class.
note: An abstract class cannot be instanciated.

yes, you can

Yes, you can. See the below code.

`public abstract class SavingAccountDetails
{
public abstract void PrintData();
}

public abstract class CurrentAccountDetails : SavingAccountDetails
{
public override void PrintData()
{
Console.WriteLine(“Current account details”);
}
}`

Sure, an abstract class can inherit from another class!!

The only time a class cannot inherit from another is when the class you wish to inherit from is sealed or has private constructors only.
