Word Analysis:
In this question, we need to identify the word that is different from the rest. Let's analyze each word given:

a) Travelled: This word refers to the action of going from one place to another, typically over a distance. It can be done by various means such as car, train, or plane.

b) Sailed: This word refers specifically to the action of traveling on water using a boat or a ship. It involves using wind or engine power to propel the vessel.

c) Walked: This word refers to the action of moving on foot, typically at a slower pace than running or jogging.

d) Rode: This word refers to the action of traveling on or in a vehicle, typically a bicycle, motorcycle, or horse.

Word Differentiation:
Now let's compare these words and identify the differences:

- Travelled, sailed, and rode all involve some form of transportation from one place to another.
- Walked, on the other hand, is the only word that specifically refers to traveling on foot.

Conclusion:
Based on the analysis, we can conclude that the word "walked" is different from the rest because it refers to a mode of transportation that does not involve any form of vehicle. The other three options all involve the use of vehicles or traveling on water. Therefore, the correct answer is option 'C' - Walked.

Travelled is like going on air, water or land.
sailed means only on water.
walked means only on land.
rode means past tense of ride also this is as well land.
So travelled includes three things but other words has only one way to move between places.
Hence this is how travelled appeared as an answer for this problem.
