In this scenario, what would be the catalyst ? The candy tablets being added to the drink. The gasses being released when the drink was first opened. The piece of paper being placed over the soft drink. The container that holds the liquid.

Explanation:

A catalyst is something that hastens a reaction, but does not really take part in it. So the candy tablets looks like a catalyst, but you have put this under English, so I'm not exactly sure what the answer should be.

It isn't D.

It could be C.

I don't think it can be B. That's not a catalyst in the true sense of the word. The bubbles show that the gasses have been released. But it is not catalytic.

I'll stick with A, but I wouldn't object to C.
