If C={0,1,2,3}, in which form is C written?
Answer and explanation
Correct answer: Roster form
The governing concept is the distinction between common set representations. In roster form, the individual elements are written explicitly inside braces and separated by commas. Since C directly lists 0, 1, 2, and 3, it is written in roster form, so option A is correct. Set-builder form would give a defining rule, a Venn representation would be graphical, and descriptive form would explain the set in words.
