Answer:
"She mixed..." - homophone
"A horse..." - pun
"I left..." - homonym.
Explanation:
Homophones are words that sound the same but are spelled differently, so flour and flower would be homophones.
Homonyms are words that are spelled the same and sound the same but have different meanings, so left as in to leave and left as in the direction are homonyms.
Puns are a method of using words with associated meanings to make jokes that usually involve wordplay. A horse being a stable animal is a pun because horses are kept in stables.
