**Core Concept**
The question is testing the understanding of **hemoglobinopathies**, specifically the abnormalities in the beta chains of hemoglobin. Hemoglobin is a tetrameric protein composed of two alpha and two beta chains, and abnormalities in these chains can lead to various diseases.

**Why the Correct Answer is Right**
Since the correct answer is not provided, let's discuss a common condition where both beta chains of hemoglobin are abnormal, which is **Beta-Thalassemia Major**. In this condition, there is a mutation in both beta-globin genes, resulting in severe reduction or absence of beta-globin chain production.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific option provided, it's challenging to give a precise reason for its incorrectness.
**Option B:** Similarly, without the specific option, it's difficult to explain why it's incorrect.
**Option C:** And **Option D:** The same applies to these options.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that **hemoglobinopathies** can be classified based on the chain affected, and understanding the specific chain involved is crucial for diagnosis and management.

**Correct Answer:** Unfortunately, the correct answer is not provided to complete this explanation.
