Concept:The underlined word is 'generous'. We need the word that is most nearly opposite in meaning and also fits the gap in the sentence.
Explanation:'Generous' means willing to give money, help, or kindness freely and more than is expected.
The most direct opposite of 'generous' is 'mean', which means unwilling to share, stingy, or ungenerous.
'Indifferent' means not caring or not interested, which is not the same as being ungenerous.
'Sympathetic' means showing concern for others, so it is closer to a positive caring attitude rather than an opposite.
'Nasty' means unpleasant or unkind, but it does not, by itself, express the idea of being ungenerous or stingy.
Therefore, the word that gives the best contrast and correctly fills the gap is 'mean'.
Answer:D. mean
