Final answer:
Henry's opinion is that part of him wants to go to have an understanding of his father, but part of him really doesn't.
Step-by-step explanation:
Based on the provided information, it can be inferred that Henry's opinion is option d. Part of him wants to go to have an understanding of what made his father who he is, but part of him really doesn't want to go. This can be seen in the dialogue between Henry and his father where Henry expresses his desire to explore Africa but also expresses his dislike for the idea of turning off the house's automated systems. This suggests a mixed opinion.
