How do you correctly override the to_s method in a Ruby class to return a custom string?

Adef to_s; print "Custom string"; end

Bdef to_s() puts "Custom string" end

Cdef to_s; "Custom string"; end

Ddef to_s; return puts "Custom string"; end

Step-by-Step Solution

Solution:

Step 1: Understand method overriding
Overriding to_s requires returning a string, not printing it.
Step 2: Analyze options
def to_s; "Custom string"; end returns the string directly. Options B, C, and D use puts or print, which output to console but return nil or unexpected values.
Final Answer:
def to_s; "Custom string"; end -> Option C
Quick Check:
puts obj.to_s prints the returned string [OK]

Quick Trick: to_s must return string, not print it [OK]
