Answer:
Medication
Explanation:
In this question, we have several options that look very similar. However, we know that we are looking for a noun because the possessive adjective "her" is the word before the blank. This means that A and B cannot be the answer. Moreover, because of the context of the sentence, we know that the right word is a synonym of the word "medicine," or a word that is very similar in meaning. Therefore, the only correct option would be "medication."
