Ruby - Control Flow

Which of the following shows the correct way to write a case/when statement in Ruby that prints "Hello" when the variable greeting is "hi"?

Acase greeting when 'hi' puts 'Hello' else puts 'Goodbye' end

Bcase greeting if 'hi' puts 'Hello' else puts 'Goodbye' end

Cswitch greeting when 'hi' puts 'Hello' else puts 'Goodbye' end

Dcase greeting when greeting == 'hi' puts 'Hello' else puts 'Goodbye' end

Step-by-Step Solution

Solution:

Step 1: Identify correct syntax
The Ruby case statement uses when clauses to match values directly, not conditions.
Step 2: Analyze options
case greeting when 'hi' puts 'Hello' else puts 'Goodbye' end correctly uses when 'hi' to match the value of greeting. case greeting if 'hi' puts 'Hello' else puts 'Goodbye' end incorrectly uses if inside case. switch greeting when 'hi' puts 'Hello' else puts 'Goodbye' end uses switch, which is not Ruby syntax. case greeting when greeting == 'hi' puts 'Hello' else puts 'Goodbye' end incorrectly uses a condition inside when.
