Ruby - Control Flow

Which of the following is the correct syntax to use a range pattern in a Ruby case statement?

Acase x; in 1..5 then puts 'Yes'; end

Bcase x; when in 1..5 then puts 'Yes'; end

Ccase x; in (1..5) puts 'Yes'; end

Dcase x; in 1-5 then puts 'Yes'; end

Step-by-Step Solution

Solution:

Step 1: Recall correct case with in syntax
The correct syntax is case variable; in pattern then action; end.
Step 2: Evaluate each option
case x; in 1..5 then puts 'Yes'; end matches this syntax correctly. case x; when in 1..5 then puts 'Yes'; end mixes when and in incorrectly. case x; in (1..5) puts 'Yes'; end misses then. case x; in 1-5 then puts 'Yes'; end uses invalid range syntax.
Final Answer:
case x; in 1..5 then puts 'Yes'; end -> Option A
