From the words or groups of words lettered A to D, choose the word or group of words that best completes the sentence.
He preferred travelling by road....travelling by air.

Answer Details

The sentence compares two modes of transportation: travelling by road and travelling by air. To indicate a preference for one option over the other, we need to use a phrase that expresses comparison. The phrase "preferred...to" is commonly used to indicate a preference for one thing over another. Therefore, the correct option is A, "to." The completed sentence would be: "He preferred travelling by road to travelling by air," meaning that he likes travelling by road more than travelling by air.
