The set of all letters in the word 'SCHOOL' in roster form is:
A{S, C, H, O, L}
B{S, C, H, L}
C{S, C, H, O, O, L}
D{S, C, H, O, O}
Answer & Solution
Correct answer: A. {S, C, H, O, L}
In roster form elements are NOT repeated. SCHOOL has letters S, C, H, O, L (O appears twice but is listed once). Order of listing is immaterial.
