This choice correctly states that there exists an x who is the father of Angelo (Fxa), is Italian (Ixa), and for all y, if y is also the father of Angelo (Fya), then y must be the same person as x (Fya ⊃ y = x). This captures the information that Angelo's father is Italian and unique in relation to other possible fathers.
