AHis own brother's only
BHis own father's only
CHis own son's
DHis own uncle's only
Answer & Solution
Correct answer: C. His own son's
1. 'I have no brother or sister' so 'my father's son' = the man himself.
2. 'That man's father is my father's son' = that man's father is himself.
3. So that man is the speaker's son.
4. Hence it is his own son's photo.
