Answer:
A. Who let the dogs out?
Explanation:
There are multiple possible answers to this question but it is scientifically proven that "yes" did not let the dogs out. If yes happened to let the dogs out, then he/she/they/xe would be required to use a capital "Y." Therefore we can conclude you cannot answer "yes" to who let the dogs out.
It is a mystery. Remember to stay cool and breath forward not backward. Take this complimentary image. Goodbye.
