h = { :city => 'Paris', 'country' => 'France' }
puts h[:country]
puts h['city']

Bnil nil

C nil

Step-by-Step Solution

Solution:

Step 1: Access :country key
The hash has a string key 'country', but h[:country] looks for a symbol key :country, which does not exist, so returns nil.
Step 2: Access 'city' key
The hash has a symbol key :city, but h['city'] looks for a string key 'city', which does not exist, so returns nil.
Final Answer:
nil\nnil -> Option B
Quick Check:
Symbol vs string key mismatch returns nil = B [OK]

Quick Trick: Access hash keys with exact symbol or string type [OK]
