Usually Mock Exams have their answers provided. Where exactly does this question come from?

What happens when you compile each of these expressions?

hello arnab,
i think u have made wrong decision in ur choices.
according to me,

choice a) is wrong because identifier 'j' is declared and initialized in "for" loop after declaring same variable 'j' inside the method before "for" loop.

choice b) is wrong because comparision part of "for" loop doesn't evaluate to a boolean value.

choice c) is correct because it follows all the rules.

choice d) is wrong because variable i is used without initializing it.

choice e) is wrong because the format of "for" loop declaration is only wrong
