I saw this online test and after going through the solutions I got confused for the explanation given concerning the correct answer to a question.
C is the correct answer and here is the reason they give:
Here C is the correct answer. Opposing triangles are point reflections. Hollow circles and arrows are already point reflected in the centre position. Therefore the blank triangle must have a filled circle in the middle, so only B or C can be correct. The arrow is always clockwise in front of the filled circle, so C is the correct answer.
But should it not be counter-clockwise instead of clockwise? (The answer would still be C)
