If G={1,2} and H={1,2,3}, which statement is correct?
Answer and explanation
Correct answer: G⊆H
The governing concept is subset notation. G⊆H means every element of G must also belong to H. Since both 1 and 2 are in H, G⊆H is true, so option A is correct. H is not a subset of G because H contains 3, which is absent from G. Therefore option B is false; 3∈G is false, and the sets cannot be equal because their elements differ.
