**Core Concept**
The patient in question exhibits a classic case of **medication-induced mania**, where tapering off medications leads to a relapse of manic symptoms. This phenomenon highlights the importance of **gradual tapering schedules** and **long-term adherence** to treatment plans in patients with bipolar disorder.

**Why the Correct Answer is Right**
The correct answer is likely **Long-Acting Injectable Antipsychotics (LAIs)**. These medications have been shown to improve adherence and reduce hospitalization rates in patients with bipolar disorder, particularly those with a history of medication non-adherence. LAIs work by providing a steady release of the active medication over time, reducing the need for frequent dosing and minimizing the risk of withdrawal symptoms. This can help patients maintain a consistent therapeutic level of the medication, thereby reducing the likelihood of manic relapses.

**Why Each Wrong Option is Incorrect**
**Option A:** **Cognitive Behavioral Therapy (CBT)** may be beneficial in addressing the psychological aspects of bipolar disorder, but it is not the most effective treatment for improving compliance in patients with a history of medication non-adherence.

**Option B:** **Lithium augmentation** may be used to enhance the efficacy of existing medications, but it does not directly address the issue of non-adherence.

**Option C:** **Mood stabilizers** are essential in the treatment of bipolar disorder, but they do not specifically address the problem of compliance.

**Clinical Pearl / High-Yield Fact**
When managing patients with bipolar disorder, it's essential to strike a balance between **symptomatic improvement** and **long-term adherence** to treatment plans. This can be achieved by using medications with a favorable side effect profile, implementing gradual tapering schedules, and incorporating behavioral therapies to address underlying psychological issues.

**Correct Answer:** C.
