Step-by-Step Solution

Solution:

The command uses -F, to split fields by commas. The condition $2 > 26 filters rows where the second field (age) is greater than 26.
Step 2: Apply the condition to each row
Rows:
- Header: 'age' > 26? No (string)
- Alice,30: 30 > 26? Yes, print $1 = Alice
- Bob,25: 25 > 26? No
- Carol,27: 27 > 26? Yes, print $1 = Carol
Final Answer:
Alice Carol -> Option D
Quick Check:
Filter ages > 26, print names [OK]

Quick Trick: Filter with $column condition and print desired field [OK]
