How can you distinguish between answer choice A & B. Every other choice seems to have some give away but these two I find very difficult to distinguish. What would be your though process?

"B" has a thinner "neck" than "A" leading up to the top of the shape. Honestly, from the picture given in the problem, it is hard for me to tell which size "neck" fits better. But seeing the TFE explanation, it would appear that "A" is the correct choice. I could be wrong, but hope that helps.

Just looked at the image again and saw that the answer actually is "A". Missed that the first time 😛

Since "B" has a thinner neck, that was my reasoning to pick answer choice B, because by looking at the actual structure in question, it seems like the neck would be thinner. doesn't it? I wanna know how people would distinguish and what are the deciding factors for their answer choice? Just like how you explained Div2388.

Hey man, choice a is correct... its very slight and this one cand be tricky but choice B's neck is too thin, you have to imagine rotating the 3d image in your head. with the view point it gives you the neck would be naturally thinner at that angle, but if you rotate an object head on it will thicken giving you answer choice A. B would goagainst that rule as it wouldn't get thinner as you rotate it flat... I'll just call you to explain it.
