Select the most appropriate option to substitute the highlighted word segment in the given sentence.
Her thinning grey hair was hanging on her bony forehead.

Correct option is C

The correct substitution of the highlighted word segment is ‘straggling over’ to make the sentence grammatically and contextually correct.
Explanation:
· Straggling over means hanging in a disordered or irregular way (अनियमित रूप से झूलना). This fits the description of thinning grey hair on her forehead.
· Correct sentence: Her thinning grey hair was straggling over her bony forehead.
Meanings of Other Options:
· (a) Falling about: Collapsing or laughing uncontrollably (गिरना/हंसना). Does not fit the context.
· (b) Urging ahead: Pushing or motivating to move forward (आगे बढ़ाना). Irrelevant here.
· (d) Sinking from: Moving downward (नीचे की ओर जाना). Does not describe hair hanging on a forehead.
