Final answer:
The line implicating Oedipus's pride is "I, Oedipus, whose fame all men acknowledge," indicating his self-awareness of his own high status and the reputation he maintains among his people.
Step-by-step explanation:
The line that supports the inference that Oedipus is a proud man is "I, Oedipus, whose fame all men acknowledge." This statement reflects Oedipus's awareness of his own reputation and status, and it suggests a certain level of self-importance and pride. The passage indicates that Oedipus holds himself in high esteem, confident in his capabilities and desiring to be seen as a savior to his people. Still, it is also useful to note that his willingness to help and pity for his people complicates a simplistic assessment of his pride as merely arrogance; it is, to an extent, matched with a sense of responsibility and care for his subjects.
