All of the above strings are valid. Option A and B are enclosed in double quotes, which is the standard way of denoting a string in Ruby. Option C uses the alternate syntax `%Q{}`, which can be used to declare a string with any kind of delimiter, and is especially useful when the string contains lots of double quotes.
