Q. The set of all letters of the word 'SCHOOL' is represented by
I. $\{ S , C , H , O , O , L \}$
II. $\{ S , C , H , O , L \}$
III. $\{ C , H , L , O , S \}$
IV. $\{ S , C , H , L \}$
The correct code is

Sets

Solution:

While writing the set in roster form, an element is not generally repeated, i.e., all elements are taken as distinct. The set of letters forming the word '$SCHOOL$' is $\{ S , C , H , O , L \}$ or $\{ H , O , L , C , S \}$. Here, the order of listing elements has no relevance. We can also express it as $\{ S , C , H , O , L \}$.
