• Answer: A and B only
  
  Reason:
  Sentence 1:
  No Ghost -> Laugh
  Some Demons -> Laugh
  Since demons can also be ghosts and some of them laugh. hence those demons cannot be ghosts.
  
  Sentence 2:
  Some Lunatic -> Guitarist
  All Lunatic -> Vocalist
  So,a vocalist may or may not be a lunatic. Some vocalists have to lunatics and since out of such lunatics some of them are guitarists,since all of them are vocalists.
  Hence, Some vocalists are guitarists.
  
  Sentence 3:
  All jesters -> colourful
  Some jesters -> Not sing
  So some jesters can sing. However if we take the fact that some some jesters who are singers,then by the third statement they are not colourful, which is a contradiction with the first statement.
  
  Sentence 4:
  This statement is grossly wrong as nothing like "Some" or "All" is mentioned in the first two statement.
