**Core Concept**
Apoptosis, or programmed cell death, is a vital process in multicellular organisms, enabling the elimination of damaged or unwanted cells. Inhibitors of apoptosis are molecules that interfere with this process, promoting cell survival and potentially contributing to various diseases.

**Why the Correct Answer is Right**
Inhibitors of apoptosis act by interfering with key regulators of the apoptotic pathway. They can bind to and inhibit pro-apoptotic proteins, such as BAX and BAK, or activate anti-apoptotic proteins like BCL-2. This balance between pro-apoptotic and anti-apoptotic signals determines whether a cell undergoes apoptosis. Inhibitors of apoptosis can be endogenous (e.g., BCL-2 family proteins) or exogenous (e.g., certain viral proteins).

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not accurately describe a known inhibitor of apoptosis.
**Option B:** This option is incorrect as it is a term that refers to a different process, not directly related to apoptosis inhibition.
**Option C:** This option is incorrect as it is a type of programmed cell death, not an inhibitor of apoptosis.

**Clinical Pearl / High-Yield Fact**
Inhibitors of apoptosis are often dysregulated in cancer, where they contribute to tumor cell survival and resistance to therapy. Understanding the mechanisms of apoptosis inhibition is crucial for developing targeted cancer therapies.

**Correct Answer:** B. BCL-2 (B-cell lymphoma 2) is a well-known inhibitor of apoptosis, which plays a critical role in regulating cell survival and death.
