Final answer:
A spoonerism is found in the example is option c) 'The doctor gave the sick patient an anecdote,' where 'antidote' is swapped with 'anecdote' for a humorous effect.
Step-by-step explanation:
A spoonerism is a play on words where the initial sounds or letters of two or more words are swapped to create a new meaning or humorous effect. It is named after the Reverend William Archibald Spooner, who was notorious for such errors.
In the examples provided, the sentence 'The doctor gave the sick patient an anecdote' is a genuine example of a spoonerism.
The correct word should be 'antidote,' but it has been humorously swapped to 'anecdote,' which refers to a short amusing or interesting story about a real incident or person, creating a nonsensical sentence.
For instance, If you say "bunny phone" instead of "funny bone," you've uttered a spoonerism. "Jelly beans" becomes "belly jeans." "Son, it is now kisstumary to cuss the bride." You get the idea.
