What did the father think about the portrait?

The father believed that the portrait bore no resemblance to him, indicating that he perceived the representation as completely inaccurate or disconnected from his actual appearance. This suggests that he found the artwork failed to capture his features or essence, preferring perhaps a more realistic portrayal.

Considering the other options, if the father thought the portrait captured his likeness perfectly, it would imply satisfaction with the artwork's accuracy. Similarly, if he believed it resembled him poorly or was an abstract representation, that would indicate some level of resemblance, whether negative or positive, which contradicts his assertion that it bore no resemblance at all. Therefore, the choice aligns with his belief that the portrait did not reflect what he looked like in any meaningful way.
