The correct answer is D. Ointment
Step-by-step explanation:
An Ointment is a topical medicine that is made using an oil base, this implies ointments contain mainly oil and only a small percentage of water. Indeed, most ointments contain 80% oil and just 20% water. This makes ointments viscous and resistant to water. Additionally, ointments differ from creams and lotions because these two are less viscous and are often created using a water base, although they can contain oil in the same proportions as water. According to this, the form of Jenna's medicine is ointment because her medicine contains 80% oil and 20% water which occurs only in ointments as creams, lotions and other forms of medicine contain less oil.
