    A Advances in artificial intelligence have transformed Correct Answer Incorrect Answer
    B industries across the world, enabling companies Correct Answer Incorrect Answer
    C to operate more efficient and deliver Correct Answer Incorrect Answer
    D personalised solutions to their customers. Correct Answer Incorrect Answer
    E no error Correct Answer Incorrect Answer

    Solution

    In C, replace the adjective efficient with the adverb efficiently, as we need an adverb to modify the verb operate (which is the action being performed). The adverb describes how the companies are operating. The corrected sentence would then read: "Advances in artificial intelligence have transformed industries across the world, enabling companies to operate more efficiently and deliver personalised solutions to their customers." Therefore, C is the correct answer.
