Show answer & explanation
Correct answer: B
Explanation
The original sentence contains grammatical errors. The subject 'it' requires the third-person singular verb 'has' instead of 'have'. The phrase 'have been designed' correctly uses the present perfect passive voice to describe a past design with present relevance. The word 'originally' is correctly placed as an adverb modifying the verb phrase. Finally, 'ones' is the correct plural pronoun to replace 'drives' (long drives vs. short ones), ensuring agreement with the plural noun 'drives' used earlier in the sentence.
