def info(options = {})
  "Name: #{options[:name]}, Age: #{options[:age]}"
end

puts info(name: "Alice", age: 30)

CName: {:name=>"Alice"}, Age: {:age=>30}

Step-by-Step Solution

Solution:

Step 1: Understand method call with hash named parameters
The method info accepts a hash options. The call info(name: "Alice", age: 30) passes a hash with keys :name and :age.
Step 2: Evaluate string interpolation
The method returns a string with values from the hash accessed by options[:name] and options[:age], which are "Alice" and 30 respectively.
Final Answer:
Name: Alice, Age: 30 -> Option D
Quick Check:
options[:name], options[:age] = Alice, 30 [OK]

Quick Trick: Access hash keys with options[:key] inside method [OK]
