Answer 2

He was laughed at by all the students.

According to the given question, the provided statement that is in active voice has been changed to one in passive voice. While making this conversion there are a few points that are to be kept in mind. They are as follows-

1. There is usually an addition of the word 'by'.
2. It is usually placed towards the end of the sentence, before the subject.
3. However, sometimes we can omit the subject.
4. But, it can be done only when the subject can be easily guessed or assumed. For example, in this case, it is better not to avoid the subject since it is difficult to completely guess it.
