The correct answer is: B. Baloon
The correct spelling of the word is "balloon".
- Ballistic is an adjective that means "of or relating to ballistics". Ballistics is the science of the motion of projectiles, especially bullets and bombs in flight.
- Bulletin is a noun that means "a brief official report or statement, especially one issued by a government or other organization".
- Bullock is a noun that means "a castrated male ox".
The word "baloon" is not a real word. It is a misspelling of the word "balloon".
