Answer:
B. Tip the bowl slightly, then spoon up the last bit
Explanation:
Generally speaking none of the other answers made much of sense.. "tip the bowl from side to side" doesn't help you at all, neither does "Keep spooning as much as you can, then stop eating". Neither of these will help you spoon up the last little bit, the most logical answer is B. "Tip the bowl slightly, then spoon up the last bit". If this is not the correct answer then it'd be D, but I don't believe/feel that it's "poor etiquette" to "leave the last little bit".
