Given the following information,which is true?
1)A occurs only if either B or C occurs
2)B occurs only if both D and E occurs
3)F occurs only if C doesnot occur
4)G occurs only if both A and F occur
options are
A.none of these
B.G doesnot occur if D doesnot occur
C.A occurs whenever
F occurs
D.F never occurs

• if D doesnot occur B will not occur..
  for occurance of G both A and F must occur..
  now as B doesnot occur, C must occur for A to occur..in that case F cannot occur..
  so if D doesnt occur G cannot occur.

• ans:a
  since a =b/c
  b=d&e
  f=!c
  g=a&f
  option 2:if d occur then g may occur only if both a &f occur
  the option is false
  option 3:a occur when b or c occur
  case 1:a occur when b occur so f can occur
  case 2:a occur when c occur where f will not occur so the statement is false
  option 4:f may occur when c doesnot occur
  the statement is false

  if B then D & E.
  G A B D E F

• B will be ans because to occur g ..a and f will occur nd to occur f c must not occur ..to occur a ..b will occur ..to occur b d and e must occur.
  so g doesnot occur if d doesnot occur

• g does not occur if d does not occur
  as g occurs when both a and f occur. f occurs when c does not occur and a occurs when b or c occurs .it means that here a occurs as b occurs
  so ans is option B
