Look at the questions asked by Rohan and Anjali.

Q. Tick the question that is the most appropriate for finding the ‘most liked subject’? Why do you think so? Discuss with your friends and teacher.

Solution:
The question asked by Anjali ‘Which subject do you like the most’ is the most appropriate for finding the ‘most liked subject’.
I think so because it asks the person to choose only one subject that they like the most. While the other question ‘Which subjects do you like’ allows person to name several subjects.
