I. Some cuboids are white → False (as all cuboids are black)

II. Some boxes are black → True (as some boxes are cuboids & all cuboids are black)

III. No box is black → False (as some boxes are cuboids & all cuboids are black)

IV. Some boxes are cuboids → True (as some cuboids are boxes)

Hence, ‘only conclusions II and IV follow’ is the correct answer.
