Haha, this graph is like a mountain roller coaster! The trend is all over the place. I'd say D, but C is probably the safest bet.

Hmm, I'm not sure. B could work too, as the variability does seem to decrease with the intervention. But I'll go with C just to be safe.

D seems like the right answer to me. The trend definitely changes between the two phases, so that's the best exemplification in this case.
