The question below has one blank, which is indicating that something has been omitted. Find out which option can be used to fill up the blank to make it meaningfully complete.
After weeks of dryness, the river ________ to a gentle trickle.

Correct option is A

The correct option to fill in the blank is (a) dwindled.
Dwindled means to become gradually smaller or less in amount—exactly what happens to a river after prolonged dryness. (Hindi: धीरे-धीरे घट जाना/कम होना).
Example: After a scorching summer, the creek dwindled to a narrow thread of water.
Explain why other options are incorrect.
· progressed: moved forward or advanced (Hindi: आगे बढ़ना); doesn’t collocate with “to a gentle trickle.”
· coagulated: became thick/semi-solid, usually of blood or liquids (Hindi: जम जाना/थक्का बनना); not used for river flow reducing.
· crossed: went from one side to another (Hindi: पार करना); grammatically/contextually off with a river as subject.
· proliferated: increased/multiplied rapidly (Hindi: तेजी से बढ़ना/फैलना); opposite of the intended sense.
