This answer is true according to adding a new key$-$value pair to the dictionary?

def dictionary$\_$operations$($self$,$ key, value$)$:

self.sanple$\_$dict$[$value$]=$key

return self.sample$\_$dict

def dictionary$\_$operations$($self$,$key, value$)$:

self.sample$\_$dict $[$key$]=$ value

return self.sanple$\_$dict

def dictionary$\_$operations$($self$,$ key,value$)$:

return self.sample$\_$dict.update$($key$,$ value$)$

def dictionary$\_$operations$($self$,$ key,value$)$:

return self.sample$\_$dict.update$($value$,$ key$)$
