Answer and explanation
Correct answer: 3 ∈ D
The symbol ∈ means “is an element of” or “belongs to.” To check a membership statement, compare the number on the left with every element listed in the set D. The number 3 appears in D, so 3 ∈ D is true. The numbers 6, 0, and 7 are absent, making options B, C, and D false. Therefore, option A is correct.
