Claims and support are related because claims are statements that are made by authors in relation to some subject matter that are backed up by "support" or evidence. Therefore, based upon these options, "An author will use support to back up a claim." This claim and support are what authors use to create arguments in writing to make a point and to express a perspective on a particular issue.
