Concept:The word 'prevalent' means widespread or commonly occurring in a particular area or time. Its synonym is a word that shares the same sense of being frequent or general.
Explanation:First, understand the meaning of 'prevalent' (सर्वव्यापी). It refers to something that is frequent or widely accepted.
For example, "Smartphones are prevalent in modern society."
Now, check each option:
- 'Unusual' (असामान्य) means not common – it is an antonym.
- 'Rare' (दुर्लभ) means happening infrequently – also opposite.
- 'Different' (विभिन्न) means not the same – does not match.
- 'Common' (आम) means occurring often or widespread – this matches exactly.
Therefore, the correct synonym is 'common'.
Answer:Option B (common) is the correct answer.
