Ruby - Modules and Mixins

Identify the error in this code:

module M
  def greet
    "Hello from M, " + super
  end
end

class C
  prepend M
end

puts C.new.greet

ANoMethodError because C does not define greet method

BSyntaxError due to missing method end

CTypeError because prepend is used incorrectly

DNo error, prints 'Hello from M, '

Step-by-Step Solution

Solution:

Step 1: Check method definitions
Module M defines greet calling super, but class C does not define greet.
Step 2: Understand super call behavior
Calling super in M's greet looks for a method in C or ancestors, but none exists, causing NoMethodError.
Final Answer:
NoMethodError because C does not define greet method -> Option A
Quick Check:
Super without method below causes NoMethodError [OK]

Quick Trick: Super requires method in next lookup, else NoMethodError [OK]
