Fill in the blank with the appropriate word.
The aviation travel industry is affected by the _______ of fog conditions.

Correct option is B

The correct option is (b).

Explanation:

• The sentence discusses how fog conditions impact aviation. What matters is how serious or intense the fog is.
• Severity means the degree of seriousness or harshness. Hence, it fits grammatically and contextually.

Correct answer word – Severity:

• Meaning: The intensity/seriousness of something. (Hindi meaning: तीव्रता / गंभीरता)
• Example: The severity of the storm caused major flight delays.

Meanings of other options:

• (a) Enactment – The passing of a law (कानून बनाना); not related to fog intensity.
• (c) Aristocracy – The noble class (कुलीन वर्ग); irrelevant here.
• (d) Urbanity – Politeness/refinement (शिष्टता); does not fit the context.

So the correct answer is (b)
