Correct Answer: Only conclusion II follows


Solution : The possible Venn diagram according to the given statements is as follows –

Let's analyse the conclusions –
Conclusion (I): Some pictures are black – Because there is a negative relation between pictures and black through the colour. So, no positive relation can be drawn between them. Therefore, this conclusion is not true.
Conclusion (II): No picture is black –  Because there is a direct negative relation between colour and black and the picture is part of the colour. Therefore, this conclusion is true.

So, only conclusion II follows. Hence, the first option is correct.
