Answer

To solve the question "Macula lutea is part of," we need to analyze each of the given options to determine which one correctly identifies the location of the macula lutea.

### Step-by-Step Solution:

1. **Understand the Term "Macula Lutea":**
- The macula lutea is a specific area in the eye that is known for its high concentration of photoreceptor cells and is crucial for central vision.

2. **Evaluate Option (a): Optic Nerve:**
- The optic nerve is responsible for transmitting visual information from the retina to the brain. It does not contain the macula lutea.
- **Conclusion:** Incorrect.

3. **Evaluate Option (b): Sclerotic (Sclera):**
- The sclera is the outer layer of the eye, often referred to as the "white of the eye." The macula lutea is not part of this outer layer.
- **Conclusion:** Incorrect.

4. **Evaluate Option (c): Choroid:**
- The choroid is the middle layer of the eye, which contains blood vessels and provides nourishment to the eye. The macula lutea is not located in this layer.
- **Conclusion:** Incorrect.

5. **Evaluate Option (d): Retina:**
- The retina is the innermost layer of the eye where light is converted into neural signals. The macula lutea is indeed located in the retina, specifically as a yellowish spot that is crucial for sharp vision.
- **Conclusion:** Correct.

### Final Answer:
The macula lutea is part of the **(d) Retina**.
