The best interpretation of the quote "others, not knowing what to do with their gold, sink into profligacy and perish like flies stuck in honey" is:
A. They are compelled by something appealing but wasteful, resulting in their demise.
This interpretation captures the idea that the individuals are drawn to the allure of their wealth (the "gold") but ultimately lead themselves to a destructive path (sinking into profligacy) because they cannot manage or wisely use their resources, similar to how flies get trapped and perish in honey.
