Select the most appropriate option to complete the given idiom.
cool as ______

Correct option is C

The correct option to fill in the blank is (c) a cucumber.
Explanation of correct answer: The idiom "cool as a cucumber" is used to describe someone who remains calm and untroubled, even in stressful situations. A cucumber is often associated with being physically cool, which is why it symbolizes calmness in this idiom. (Hindi meaning: अत्यधिक शांत और संयमित)
Example: Even during the tense negotiation, she was as cool as a cucumber.
Why other options are incorrect:
· Option (a): air Air does not fit the idiom because it does not convey the idea of calmness or composure that "cucumber" does. (Hindi meaning: हवा)
· Option (b): ice Ice might seem appropriate due to its coolness, but the established idiom uses "cucumber" to describe calmness. (Hindi meaning: बर्फ)
· Option (d): a river A river can be calm, but the idiom "cool as a cucumber" is the correct and common phrase used in English. (Hindi meaning: एक नदी)
