Concept:The error lies in the use of "it’s" (contraction for "it is" or "it has") instead of the possessive determiner "its".
Explanation:In part (c), the phrase "in it's people" is incorrect.
"It’s" is a contraction, meaning "it is" or "it has".
Example: "It’s a sunny day." (correct) or "It’s been fun." (correct).
"Its" is a possessive pronoun, meaning "belonging to it".
Example: "The cat licked its paw." (correct).
Here, the sentence talks about "the spirit of tolerance" that belongs to "the people of India".
Thus, the possessive form "its" is required, not the contraction "it’s".
Therefore, part (c) contains the error.
The correct sentence should read: "India's strengths are its diversity of culture and the spirit of tolerance in its people."
Answer:The error is in part (c).
