Answer #1

Ans d) All of the above

The small nanoparticles are very useful for catalysis , as they have large surface area to volume ratios. They have reactive surface sites , which help the substrate to get converted into products easily and efficiently. Thet have altered electronic structures for small sizes. So all these properties make them very useful for catalysis.
