Concept:The correct idiom is "cut a sorry figure", meaning to make a poor or unfavorable impression.
Explanation:The given phrase "cut a sad figure" is not a standard English idiom.
The idiomatic expression is always "cut a sorry figure".
It refers to appearing in a way that makes others view one negatively.
In the sentence, the girl created a bad impression during her first stage performance.
Therefore, the underlined part must be replaced with "cut a sorry figure".
Option (c) provides this correct substitution.
The other options—"made a sorry" and "cut a sorry face"—are not idiomatic or grammatically standard.
Option (d) "No improvement" is incorrect because the original phrase is flawed.
Thus, the improvement is necessary.
Answer:(c) cut a sorry figure
