How can you use a case/when statement to check multiple values in one when clause?

status = 'pending'

Acase status when 'pending' && 'waiting' && 'queued' puts 'In progress' else puts 'Other' end

Bcase status when ['pending', 'waiting', 'queued'] puts 'In progress' else puts 'Other' end

Ccase status when 'pending' || 'waiting' || 'queued' puts 'In progress' else puts 'Other' end

Dcase status when 'pending', 'waiting', 'queued' puts 'In progress' else puts 'Other' end

Step-by-Step Solution

Solution:

Step 1: Understand multiple values in when
Ruby allows comma-separated values in a single when clause to match any of them.
Step 2: Analyze each option
case status when 'pending', 'waiting', 'queued' puts 'In progress' else puts 'Other' end uses commas correctly. case status when ['pending', 'waiting', 'queued'] puts 'In progress' else puts 'Other' end uses an array which does not match directly. Options C and D use logical operators incorrectly.
Final Answer:
case status when 'pending', 'waiting', 'queued' puts 'In progress' else puts 'Other' end -> Option D
