Concept:The word "miserly" means being stingy or unwilling to share money or possessions.
The sentence uses "yet" to show a contrast between what the children think and how the uncle actually behaves.
Explanation:The children believe their uncle is miserly, meaning ungenerous.
However, the word "yet" tells us the second part should be the opposite of miserly.
Among the choices, "generous" is the direct opposite of "miserly."
If he were friendly, strict, or wicked, the contrast would not clearly match the meaning of miserly.
Therefore, the most suitable word to complete the sentence is "generous."
Answer:Option B (generous)
