• A. At
• B. In
• C. By

Answer 1

The correct option is D On

A preposition is a word which comes before a noun or a pronoun and establishes a relationship between the elements of a clause or words. Option D)on is correct as it indicates a medium of travelling. The other options are wrong as at, in, and by indicate a specific location, inside something, and usage respectively. These uses don't fit in the given question. The correct answer is D)on.
