If 45-[28-{37-(15-*)}]= 59, then * is equal to:	Choose the correct option:
A) - 29	B) - 19	C) 20	D) 29	E) 39

Rationale: "45 - [ 28 - { 37 - ( 15 - * ) } ] = 59 = > 45 - [ 28 - { 37 - 15 + * } ] = 59 45 - [ 28 - 37 + 15 - * ] = 59 = > 45 [ 43 - 37 - * ] = 59 45 - [ 6 - * ] = 59 = > 45 - 6 + * = 59 39 + * = 59 = > * = 59 - 39 = 20 answer : c"
