Is That Monk's Reaction a Bonus Action?

Every turn, in every like play or turn, has four actions. There's the action, which is usually attack or spell, there's bonus action, there's move action, and then your reaction - you actually spend it not on your turn but when you did an attack of opportunity last round. So i am going to say, using that logic, i will give you vantage on an anmel handling. Check just to see if he lets you approach without contention. And next is devo. Devo is going to, as best he can, approach the polar bear. This guy is my friend, right? Mepoa, yes. But it is also a wild and wounded animal
