The correct answer is: E. No error
The sentence is grammatically correct. The subject and verb agree, and the tense is consistent throughout. The prepositional phrase “between twenty to thirty rupees” is correctly placed after the verb “range.”
The other options are incorrect because they contain grammatical errors. Option A is incorrect because the article “the” is not needed before the noun “daily wages.” Option B is incorrect because the preposition “of” is not needed before the noun “workers.” Option C is incorrect because the article “the” is not needed before the noun “factory.” Option D is incorrect because the prepositional phrase “between twenty to thirty rupees” is not correctly placed after the verb “range.”
