Solution

The correct option is B Water in bucket B is hotter than water in bucket A.
Himanshu’s left hand felt hotter after dipping in normal water. This means that the water in the normal bucket is at a higher temperature than that of bucket A. Similarly, we can conclude that water in the normal bucket is at a lower temperature than that of water in bucket B because his right hand felt colder. The order of temperatures in the buckets is:
Bucket A < Normal Bucket < Bucket B
Therefore, bucket A has colder water and bucket B has hotter water.
