The correct answer is: d) All of the above

Folk songs are a type of traditional music that is passed down orally from generation to generation. They often tell stories about real people and events, and they can be used to teach lessons or express emotions. The lyrics of folk songs often use symbolism and metaphors, historical references, and humor and wit.

• Symbolism and metaphors are used in folk songs to add depth and meaning to the lyrics. For example, in the song “John Henry,” the hammer that John Henry uses to pound the steel is a symbol of his strength and determination.
• Historical references are used in folk songs to connect the song to a particular time or place. For example, in the song “The Ballad of John Brown,” the lyrics refer to the historical figure John Brown, who led a raid on Harpers Ferry in 1859.
• Humor and wit are used in folk songs to make the song more enjoyable and to add a touch of personality. For example, in the song “The Farmer in the Dell,” the lyrics are full of puns and wordplay.

All of these elements can be found in the lyrics of many different folk songs. They help to make folk songs a unique and enjoyable form of music.
