In similar figures the statement is written in such a way so that corresponding sides and equal angles are placed at same place .
The given similarity statement can be written as KLMN ~ PQRS
The question is asking us to find the angle which corresponds to <N
In the statement N occurs at the last place in the letter KLMN so we will look at the same place in the letter PQRS,
The letter S occupies the same place as N
So we say <N corresponds to <S
The first option is right
