end

class C
  include M

Step 1: Analyze module_eval string syntax
The string passed to module_eval defines method greet correctly with a semicolon separating statements.
Step 2: Check method availability and call
Class C includes M, so greet is available to instances. Calling C.new.greet prints 'Hi'.
Final Answer:
No error; code runs and prints 'Hi'. -> Option B
Quick Check:
module_eval string defines method correctly = C [OK]

Quick Trick: Check string syntax carefully; semicolon separates statements [OK]
