How can you dynamically create a class that inherits from BaseClass and adds a method describe returning 'Dynamic'?

ADynamicClass = Class.new(BaseClass) do def describe 'Dynamic' end end

BDynamicClass = Class.new do def describe 'Dynamic' end end < BaseClass

CDynamicClass = Class.new(BaseClass) { def describe 'Dynamic' end }

DDynamicClass = Class.new < BaseClass do def describe 'Dynamic' end end

Step-by-Step Solution

Solution:

Step 1: Recall syntax for inheritance with Class.new
To inherit, pass superclass as argument: Class.new(Superclass).
Step 2: Check method definition block
Use do...end block to define methods inside the new class.
Final Answer:
DynamicClass = Class.new(BaseClass) do def describe 'Dynamic' end end -> Option A

Inheritance via argument, methods in block [OK]

Quick Trick: Pass superclass to Class.new, define methods in block [OK]
