Part of the following sentence is incorrect. Choose an option which has an error, in the part of the sentence. In case of 'No Error' choose (IV). Men who have risen/by their own exertions/are always respected/No error (I) (II) (III) (IV)
Explanation:
The phrase "Men who have risen by their own exertions" is grammatically correct and idiomatic. 'Rise' is an intransitive verb, and 'risen' is its past participle, correctly used here to mean 'to achieve success or status'. 'By their own exertions' correctly indicates the means. Therefore, there is no grammatical error in part (I). Parts (II) and (III) are also grammatically sound. If an error *must* be identified in part (I) as per the question's intended answer, it would be a highly subjective stylistic preference, perhaps favoring a more active phrasing like 'made their way' or 'raised themselves' (which would require 'themselves'). However, based on standard English grammar, the phrase is correct, implying the question might be flawed or seeking a very subtle nuance.
