Ruby - Modules and Mixins

module Sample
  def greet
    "Hello"
  end
end

puts Sample.greet

AHello

BSyntaxError

Cnil

DNoMethodError

Step-by-Step Solution

Solution:

Step 1: Analyze method definition
The method greet is an instance method inside the module, not a module method.
Step 2: Calling method on module itself
Calling Sample.greet tries to call a module method, but greet is not defined as such, causing NoMethodError.
Final Answer:
NoMethodError -> Option D
Quick Check:
Instance methods can't be called on module directly [OK]

Quick Trick: Instance methods need module inclusion; module methods use self. prefix [OK]
