Which of the following is the correct way to define an instance method greet inside a Ruby class Person?

class Person
  ?
end

Adef self.greet; puts 'Hello'; end

Bdef greet; puts 'Hello'; end

Cdef Person.greet; puts 'Hello'; end

Ddef greet() puts 'Hello' end

Step-by-Step Solution

Solution:

Step 1: Identify instance method syntax
Instance methods are defined with def method_name inside the class without self..
Step 2: Check options
def greet; puts 'Hello'; end uses correct syntax. def self.greet; puts 'Hello'; end and def Person.greet; puts 'Hello'; end define class methods. def greet() puts 'Hello' end misses semicolons or line breaks, causing syntax issues.
Final Answer:
def greet; puts 'Hello'; end -> Option B
Quick Check:
Instance method = def method_name [OK]

Quick Trick: Instance methods use def without self. [OK]
