Correct answer: D — No anticoagulation needed

A CHA₂DS₂-VASc score of 1 attributable solely to female sex does not warrant anticoagulation. Female sex is a risk modifier rather than an independent indication. The effective score in this patient is 0 for the purposes of anticoagulation decision-making. No anticoagulation is needed.
