Answer: (D)

if neither conclusion I nor conclusion II follows.

Analyzed statement: No note is a coin,Some coins are metals,Some notes might also be metals.All plastics are notes,but Some notes are Plastics.

No metal is plastic: As shown in the figure some metals may be plastic.Those notes which are plastic can also be metals.Hence, Conclusion 1 doesnt follow

All notes are plastics: All notes cant be plastics.Some notes can also be metals and some notes can be neither plastic nor metals.So conclusion 2 doesnt follow.
