If L={a,b,d}, which statement is correct?
Answer and explanation
Correct answer: b∈L
In roster notation, the symbols inside braces are the elements of the set. Since a, b, and d are explicitly listed in L, the statement b∈L is true, so option A is correct. The symbol c is absent, making c∈L false. The statement d∉L is also false because d is present. Finally, L∈b reverses the usual membership relation and is not justified by the given information.
