Correct answer: (B) 2, 3 & 4 only

Explanation

A literature review must answer what type of research has been done, what methods were used and what area remains uninvestigated.

It surveys existing knowledge to locate the gap the new study will fill.

Reviewing methods shows which approaches have worked in the field.

Identifying the untouched area justifies the fresh research question.

What should not be investigated is not a review's task.

Judging what methods should never have been used misreads the review's aim.
