Which option replaces the question mark? (2 marks) [Figure description: A rule reference panel showing four symbol transformations: (1) a green circle-with-horizontal-lines operator 'Changes shading of 1st and 3rd items'; (2) a green diamond-in-circle operator 'Removes shading from 1st and 2nd items'; (3) a green Y-in-circle operator 'Replaces 1st item with copy of 3rd item'; (4) a green slashed-oval operator 'Mirrors entire sequence in y axis'. Below, a puzzle: an input sequence of three shapes (open circle, small filled triangle, outlined pencil) goes through an operator in a green circle with a question mark and becomes an output sequence (open circle, outline triangle, filled pencil). Options: A: only the striped-circle operator; B: striped-circle or the diamond-in-circle operator; C: only the Y-in-circle operator; D: only the diamond-in-circle operator.]
- A. A
- B. B
- C. C
- D. D
Answer: D. D
