**Core Concept**
Color blindness, also known as color vision deficiency, is a condition where a person has difficulty perceiving certain colors. This condition is often related to **genetic mutations** that affect the **retina** and its ability to detect colors. The most common forms of color blindness are **red-green color blindness**.

**Why the Correct Answer is Right**
The correct answer is related to the fact that color blindness is often **hereditary**, meaning it is passed down from parents to their children through **genetic inheritance**. This is especially true for **red-green color blindness**, which is usually inherited in an **X-linked recessive pattern**. This means that **males**, who have only one X chromosome, are more likely to be affected than **females**, who have two X chromosomes.

**Why Each Wrong Option is Incorrect**
**Option A:** Age-related color blindness is not a primary cause of color vision deficiency. While **aging** can affect color vision, it is not the primary reason for color blindness.
**Option C:** Color blindness is not exclusive to **males**, although they are more likely to be affected due to the **X-linked recessive inheritance pattern**.
**Option D:** Color blindness is not limited to **females**, who are typically carriers of the condition rather than being affected themselves.
**Option E:** While some forms of color blindness can be **managed** with technology or other aids, there is no definitive **treatment** to completely cure the condition.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that **red-green color blindness** is the most common form of color vision deficiency and is often inherited in an **X-linked recessive pattern**. This means that **females** can be carriers of the condition, even if they are not affected themselves.

**Correct Answer:** B. Hereditary
