Homework Statement
https://imgur.com/LYaudl1
Here is the question! Basically, we have to come up with a (reasonable) solution to all of the answer choices. It IS multiple choice, so only 1 answer is right (it is D), but we still have to find a way someone might have slipped up and made a mistake.
Homework Equations
p = mv
The Attempt at a Solution
So, I understand how to get C, D, and E. I drew a diagram and combined the vectors so the vector of the 3m mass is √2mV. And since that momentum is equal to 3mv, I solved to get v = (√2/3)V. Then for C that would just be someone making it in the opposite direction. And for E that would be solving until √2mV and leaving it as that. But I'm so lost on how someone would get 1/√3. Please help! I have been trying for 1.5 hours + and still haven't gotten anywhere.

Here is the diagram I drew. It's basically an extension of the one in the question above.
