If P={a,b,c}, which statement is correct?
Answer and explanation
Correct answer: a∈P
The governing concept is set membership. In P={a,b,c}, the symbols a, b, and c are explicitly listed as elements of P, so a∈P is true. The symbol d is absent, making d∈P false, and c∉P is false because c is present. Membership is written from an element to the set; P∈a reverses the relationship and is not justified. Therefore option A is correct.
