I prefer travelling on train than travelling by bus as I suffer from motion sickness.
Show answer & explanation
Correct answer: B
Explanation
The original sentence has two errors:
Preposition for transport: When referring to a mode of transport in general, we use 'by' (e.g., by train, by bus), not 'on' or 'in'.
Comparison structure: The verb 'prefer' is followed by 'to' to indicate comparison, not 'than' (e.g., prefer A to B).
