In Ruby, ChildClass < ParentClass returns true if ChildClass is a subclass of ParentClass, otherwise false.
Step 2: Analyze the code
Dog < Animal returns true because Dog inherits from Animal. Cat < Animal returns false because Cat does not inherit from Animal.
Final Answer:
true false -> Option A
Quick Check:
Dog is subclass of Animal [OK]

Quick Trick: Subclass check with < returns true only if inheritance exists [OK]
