Answer:
Secret is object so it will be placed as subject,Seema is subject so it will be placed as object,it is line of passive so WAS is used. Hope u understand.When the subject in an active voice sentence is a negative indefinite pronoun such as nobody, no one, this has to be changed to ��by + anybody, anyone�� in the passive voice sentence. The word ��not�� then has to be added to the predicate verb. So here the verb gets negated, not the noun.
