Any element of a set is a member of that set.
The symbol ∈ is used to denote the member of a set.
Member of a set is always the subset of its parent set.
Set A= {1, 4, 5, 7, 9, 12} implies that the elements or members of set A are 1, 4, 5, 7, 9, and 12
A, B, D, F, G, I, K, R, and Y are the members or the element of set X.
We can write as A ∈ X, B ∈ X, D ∈ X, F ∈ X, G ∈ X, I ∈ X, K ∈ X, R ∈ X, and Y ∈ X.
A. R
B. B
C. P
D. Z
Correct Answer: A
Step 1: Any element of a set is a member of that set.
Step 2: Here, only 'R' is a member of the given set.
{A, C, D, F, G, R, T, W, Y} as 'R' is contained in the set.
