Question

The set of all letters of the word $"DIFFERENTIATION"$ can be written in roster form as:

• A. $\{I,F,F,E,R,E,N,T,I,A,T,I,O,N\}$
• B. $\{D,I,F,E,R,N,T,A,O\}$
• C. $\{D,I,F,F,E,R,E,N,T,I,A,T,I,O,N\}$
• D. $\{D,I,F,E,R,E,N,A,T,I,O\}$

Answer 1

The correct option is B $\{D,I,F,E,R,N,T,A,O\}$

While writing a set in roster form, we exclude all the repeatitive elements.
So, the word $"DIFFERENTIATION"$ can be written in roster form as:
$\{D,I,F,E,R,N,T,A,O\}$
