The correct answer is A. To distract the reader from the main plot
Explanation:
In literature, a subplot refers to a plot or story that is developed along with the main story. The main purpose of doing this, it that a secondary plot or subplot allows the author to enrich the main plot usually by supporting the theme of the main plot through the secondary plot or develop more extensively other aspects such as characters, conflict or settings. However, the subplot is not used to distract the reader from the main plot, because the main purpose of a subplot is to support the main plot rather than making it less important.
