The treatment of relapsing-remitting multiple sclerosis (RRMS) involves disease-modifying therapies (DMTs) that aim to reduce the frequency and severity of relapses. **Disease-modifying therapies** include several classes of medications.

**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss the general approach to treating RRMS. Treatment options for RRMS include **interferon beta**, **glatiramer acetate**, **fingolimod**, and **natalizumab**, among others. These medications work by modulating the immune system to reduce inflammation and prevent damage to the central nervous system.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option, it's challenging to provide a detailed explanation.
**Option B:** Similarly, without the specific option, it's difficult to explain why it's incorrect.
**Option C:** And again, lacking the specific option, a precise explanation cannot be given.
**Option D:** This option also cannot be addressed without knowing what it entails.

**Clinical Pearl / High-Yield Fact**
A key point in treating RRMS is selecting the appropriate **disease-modifying therapy** based on the patient's specific condition, including the frequency of relapses and the presence of any contraindications.
