Surely that's wrong??? Template C should inherit from template B other it won't work will it?

On line 36 why is it not HELLO World? If in the parent template the HELLO is in all caps?

{{ block.super }} will render the same content present in the current block of extended template.
Thus, in this case, HELLO World
