Option 1 -> The passage argues against external dependence, not for it as a resilience-building tool.
Option 2 -> The passage emphasizes that virtue and happiness come from within, not from external control.
Option 3 -> This directly aligns with the passage's statement that allowing others to control one's peace of mind "gives them undue power over one's emotions."
Option 4 -> The passage does not suggest external control is necessary for relationships; instead, it advocates for self-determined happiness.
Hence, Option 3 -> The passage explicitly states that "Allowing others to control one's peace of mind gives them undue power over one's emotions," where "undue" means unreasonable or excessive. This matches Option 3's wording perfectly and reflects the core message that happiness should be self-determined rather than controlled by external forces or other people's actions -> correct
