B. Photoreceptor cells `to` Ganglion cells ` to` Bipolar cells
C. Ganglion cells `to` Bipolar cells `to` Photoreceptor cells
D. Photoreceptor cells `to` Bipolar cells `to` Ganglion cells

Answer

To determine the order of the three layers of cells in the retina of the human eye from inside to outside, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Layers of the Retina**: The retina consists of three main types of cells arranged in layers: ganglion cells, bipolar cells, and photoreceptor cells.

2. **Understand the Arrangement**:
- The **innermost layer** (closest to the vitreous body of the eye) is made up of **ganglion cells**. These cells receive signals from the bipolar cells and send visual information to the brain via the optic nerve.
- The **middle layer** consists of **bipolar cells**. These cells act as intermediaries, receiving input from the photoreceptor cells and transmitting it to the ganglion cells.
- The **outermost layer** contains **photoreceptor cells** (rods and cones) that are responsible for detecting light and converting it into neural signals.

3. **Arrange the Layers from Inside to Outside**:
- Starting from the innermost layer to the outermost layer, the order is:
- **Ganglion cells** (innermost)
- **Bipolar cells** (middle)
- **Photoreceptor cells** (outermost)

4. **Select the Correct Option**: Based on the arrangement, the correct order of the layers from inside to outside is:
- **Ganglion cells → Bipolar cells → Photoreceptor cells**

### Final Answer:
The order of the three layers of cells in the retina of the human eye from inside to outside is:
**Ganglion cells → Bipolar cells → Photoreceptor cells.**
