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): No card is a frame – According to the Venn diagram, there is no definite relation between a card and a frame. So, no card is a frame is a false conclusion. Conclusion (II): All pictures can never be lenses – According to the Venn diagram, part of the frame that is a picture can not be lenses. Therefore, all pictures can never be lenses is a true conclusion. Conclusion (III): At least some cards are lenses – According to the Venn diagram, there is no definite relation between cards and lenses. Therefore, at least some cards are lenses is a false conclusion.
Therefore, only conclusion II follows. Hence the first option is correct.
