Why the answer is C, and why the others tempt you.
Taxonomic ranks become progressively more specific from Kingdom down to Species. Two organisms sharing the same family are more closely related than two organisms that share only a higher, broader rank such as Class or Order. They cannot share the same genus since they belong to different genera, and they certainly belong to the same kingdom since they share a family.
