What is Peter's father's name?

The correct answer is that Peter's father's name is Maximo Tan Jr., which is evident from understanding common naming conventions and familial relationships in various cultures. In many traditions, a son carries a variation of his father's name or a name that indicates the father-son relationship.

Given the context, the name "Peter Wong" provides the information that Peter's last name is likely inherited from his father. If one considers cultural naming patterns and choices, "Maximo Tan Jr." suggests that he is likely the named father of a son, hinting at a direct familial relationship.

In contrast, the other names do not fit as well within the context of a direct father-son relationship with Peter. Chang Tai Wong and Yam Fong Wong could both potentially be linked to Peter through family, but those names do not offer the same clarity of relationship indicating they are not recognized as Peter's immediate paternal connection. The name Peter Wong points towards Maximo Tan Jr. as a grounded choice within the structure of family names and relationships presented.
