The correct answer is A. What do the images look like?
Step-by-step explanation:
In sources evaluation, the credibility refers to whether a source can be believed and therefore whether the writer can use this source as part of a paper or research. Although, this is difficult to determine there are few principles to be considered this includes whether the sources provide evidence and it is objective; the credentials or background of the author; the purpose of the text and the date it was written. On the other hand, the images a text has or not do not show whether the information is reliable and therefore, the one that is not a question you should ask when evaluating a source for credibility is "What do the images look like?" because this is not related to whether the information included in the source is valid and therefore the source is credible.
