I'm assuming "dudes and dudettes bathing in the sea" isn't the answer you're looking for, so I'll be serious. This picture is called "The Triumph of Venus", which depicts an iconic image of Venus, the goddess of beauty, who was born in the water and arrived on the land.

Just left to my own devices, I would have picked Stretch and/or Squash. The next closest thing (out of those three) is exaggeration. When you read the description of exaggeration, you find that physical characteristics can be exaggerated, but they should resemble some form of reality.
The second one is really a very close call. You could make a case for either secondary action, or follow through. The only one you could eliminate is pose to pose. That is reserved for how the action goes from one pose to another. That is more of a problem in technique than overall plotting. I think I'd pick follow through, because the character has stopped bouncing the ball, but he likely hasn't stopped sweating nor looking at his watch.
Pretty interesting question. You are not going to get asked that every day.
