module M
  def greet
    "Hi"
  end
end

class E
  include M
  def greet
    super + " there"
  end

BError: super called without a method to override

CError: Module methods cannot be called with super

DNo error; output is 'Hi there'

Step-by-Step Solution

Solution:

Step 1: Understand super with modules
When a class method calls super, it looks up the method in included modules.
Step 2: Check method lookup
Class E's greet calls super, which calls greet in module M returning "Hi".
Final Answer:
No error; output is 'Hi there' -> Option D
Quick Check:
super calls module method correctly = D [OK]

Quick Trick: super works with included module methods [OK]
