Which of the following is the correct syntax to define a method named greet using define_method that returns "Hello"?

Adef define_method(:greet) "Hello" end

Bdefine_method greet { return "Hello" }

Cdefine_method(:greet) { "Hello" }

Ddefine_method(:greet, "Hello")

Step-by-Step Solution

Solution:

Step 1: Recall correct define_method syntax
The correct syntax uses a symbol for the method name and a block: define_method(:name) { ... }.
Step 2: Check each option
def define_method(:greet) "Hello" end uses def incorrectly. define_method greet { return "Hello" } lacks symbol (greet undefined). define_method(:greet, "Hello") passes string instead of block. B matches correct syntax.
Final Answer:
define_method(:greet) { "Hello" } -> Option C
Quick Check:
Correct syntax uses symbol and block [OK]

Quick Trick: Use symbol and block for define_method syntax [OK]
