Step-by-Step Solution
Solution:
Step 1: Analyze
This prints each inner array on a separate line without quotes, so output is: [1, 2] [3, 4]puts [["1", "2"], ["3", "4"]]Step 2: Analyze
This prints the array on one line but without quotes around elements, so output is: [[1, 2], [3, 4]] (no quotes)print [["1", "2"], ["3", "4"]]Step 3: Analyze
p [["1", "2"], ["3", "4"]]pprints the inspect form, showing quotes if strings and the full structure on one line, exactly as the array looks.Step 4: Analyze
This converts the array to string and prints it with a newline, but inner elements are not quoted as inspect would show.puts [["1", "2"], ["3", "4"]].to_sFinal Answer:
p [["1", "2"], ["3", "4"]] -> Option AQuick Check:
p prints full inspect form on one line = D [OK]
Quick Trick: Use p to print full structure with quotes on one line [OK]
Common Mistakes:
- Using puts which prints each element on separate lines
- Using print which lacks quotes
- Using to_s which loses inspect formatting
