the answer says that a default method can be overridden with a protected method coz less restrictive is allowed. From what i have studied, more restrictive is allowed, less restrictive isnt. Please clarify.

In this case, the game is correct. Less restrictive is allowed.
Think of polymorphism. If you made it more restrictive, would stuff that is not directly aware of the more restrictive method be allowed to have access? Nope. Therefore, you have a breakdown of polymorphism. If you allow less restriction, polymorphism still works!
One way to be sure -- warm up that compiler and try it out!
