How can you combine keys and values methods to print each key and value on one line from a hash h?

Ah.each { |k| puts k }

Bh.keys.zip(h.values).each { |k, v| puts "#{k}:#{v}" }

Ch.values.each { |v| puts v }

Dh.keys.each { |k| puts k }

Step-by-Step Solution

Solution:

Step 1: Understand keys and values methods
keys and values return arrays of keys and values respectively.
Step 2: Combine keys and values
Using zip pairs keys and values into arrays of pairs.
Step 3: Iterate and print pairs
Using each on zipped array prints each key-value pair on one line.
Final Answer:
h.keys.zip(h.values).each { |k, v| puts "#{k}:#{v}" } -> Option B
