B. 300-2600nm
C. 390-760 nm
D. 650-760nm

Explanation

To answer the question regarding the visible part of the electromagnetic spectrum and its wavelength range, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Electromagnetic Spectrum**:
- The electromagnetic spectrum includes all types of electromagnetic radiation, which vary in wavelength. The visible part of this spectrum is the range that can be detected by the human eye.

2. **Identifying the Wavelength Range**:
- The visible light spectrum is typically defined as the range of wavelengths from approximately 390 nanometers (nm) to 760 nanometers (nm).

3. **Listing the Colors of Visible Light**:
- Within this range, visible light is divided into different colors, commonly remembered by the acronym "VIBGYOR":
- Violet: 390 - 430 nm
- Indigo: 430 - 470 nm
- Blue: 470 - 500 nm
- Green: 500 - 550 nm
- Yellow: 550 - 600 nm
- Orange: 600 - 650 nm
- Red: 660 - 760 nm

4. **Final Answer**:
- Therefore, the visible part of the electromagnetic spectrum consists of radiations having a wavelength in the range of **390 to 760 nanometers**.
