The correct answer is: another.
The word “other” is used to refer to something that is different from the one that has already been mentioned. In this case, the speaker has already read one novel by Premchand, so they are looking for another novel by him to read.
The word “another” can also be used to refer to a second or additional thing of the same kind. In this case, the speaker is looking for a second novel by Premchand to read.
The word “all” is used to refer to the whole of a group or number of things. In this case, the speaker is not looking for all of Premchand’s novels to read, just another one.
The word “few” is used to refer to a small number of things. In this case, the speaker is not looking for a small number of Premchand’s novels to read, just another one.
