which of following true:A occur only B or C occur B occur D&E occurf occur if Cnot occur g occur if A and F occur option A occur whenever F occur2)F never occur3) G not occur if D not occur4)none of these

• 3) g nt occure i d not occure
  a=>b or c
  b=>d & e
  f=>c not
  g =>a & f
  1) a occure whenevr f :- depen on c where as 'a' can occure if 'c' not ..so this is not true
  2) f nevr occure => depnd on c only n c is indipendent ...if c not occure f will occure ....so this is also not true
  3) g not occure if d not:-g depnd on a & f ...if d not ocuure b will not occure (as b=>d&e) a will occure if c occure...if c occure f will not occure ...hence g will not occure...this is true
