Let's consider this from an expected value point of view. I'm probably:
98% to make the layup --> 50K * 0.98 = 49K EV
70% to make the free throw --> 100K * 0.7 = 70K EV
30% to make the top of the key 3 --> 500K * 0.3 = 150K EV
20% to make the wing 3 --> 750K * 0.2 = 150K EV
10% to make the corner 3 --> 1000K *0.1 = 100K EV
So if the value of money is linear to me, I'm probably going with the top of the key 3.
However, the value of money isn't necessarily linear, might be closer to logarithmic. I'd consider the free throw. But probably the top of the key 3. It'd be hard to pass up a 5x increase in payoff for a shot from 7 feet farther away.
Edit: can I revise my answer? If it's shooting on that court, the corner "3" looks like it's about 16 feet. I'll go with that one lol
