puts person[:name]

Step-by-Step Solution

Solution:

The hash has a symbol key :name and a string key 'age'. Access must match key type exactly.
Step 2: Evaluate each puts statement
person[:name] returns 'Bob'; person['age'] returns 25; person['name'] returns nil because 'name' key as string does not exist.
Final Answer:
Bob 25 nil -> Option D
Quick Check:
Key type must match to access value [OK]

Quick Trick: Access hash values with exact key type used [OK]
