    Question

    $ A={x∣x=2k,k∈Z}B={x∣x=2k+1,k∈Z}C={x∣x=2(k+1),k∈Z}D={x∣x=2k−1,k∈Z}\begin{aligned} A & = \left \{ x \mid x = 2k, k \in Z \right \}\\ B & = \left \{ x \mid x = 2k + 1, k \in Z \right \}\\ C & = \left \{ x \mid x = 2(k + 1), k \in Z \right \}\\ D & = \left \{ x \mid x = 2k - 1, k \in Z \right \} \end{aligned}

    $ Which of these sets are equal to each other?


    1. FALSE: A = B, B = C
    2. FALSE: A = B, C = D
    3. FALSE: A = C, B = C
    4. TRUE: A = C, B = D
    5. FALSE: A = D, B = C
    6. FALSE: A = D, B = D

    1. A = B, B = C: Incorrect
    2. A = B, C = D: Incorrect
    3. A = C, B = C: Incorrect
    4. A = C, B = D: Correct
    5. A = D, B = C: Incorrect
    6. A = D, B = D: Incorrect
