Answer 1

def flatMap[B](f: A => Option[B]): Option[B] = 
  this match {
    case None => None
    case Some(a) => f(a)
  }

This is a simple example where how the flatMap works for Option, this can help to understand better, It is actually composing it is not adding a wrapper again.That's what we need.
