डेंनी एका व्यक्तीच्या रंगीत तैलचित्राकडे निर्देशन करत म्हणाला, "त्याचे वडील हे माझ्या वडिलांचा मुलगा आहेत." जर यातल्या 'मी' ला एकही भावंड नसेल तर चित्रातील व्यक्तीचे या संबंधातील 'मी' शी नाते काय ?

The correct answer is Option B (Son).

Key Points:
• This is a classic pointing-to-a-photograph blood relation puzzle.
• Break down the statement: 'His father is my father's son'.
• First, evaluate the second part: 'my father's son'. Since Denny says he has no siblings, 'my father's son' can only be Denny himself.
• Now substitute 'Denny' back into the first part: 'His father is Denny'.
• If the person's father is Denny, then the person in the portrait must be Denny's son.
• Key Takeaway: If you have no siblings, 'your father's son' is yourself.
