C. ultraviolet region
D. micorwave region

Explanation

To find the appropriate electromagnetic radiation required to dissociate a carbon monoxide molecule into carbon and oxygen atoms, we need to calculate the frequency of the radiation based on the energy required for dissociation, which is given as 11 eV.

### Step-by-Step Solution:

1. **Convert Energy from eV to Joules**:
The energy required for dissociation is given in electron volts (eV). We need to convert this to joules (J) using the conversion factor:
\[ 1 \text{ eV} = 1.6 \times 10^{-19} \text{ J} \]
Thus,
\[ E = 11 \text{ eV} = 11 \times 1.6 \times 10^{-19} \text{ J} = 1.76 \times 10^{-18} \text{ J} \]

2. **Use the Energy-Frequency Relation**:
The relationship between energy (E), frequency (ν), and Planck's constant (h) is given by:
\[ E = h \nu \]
Rearranging this formula to find frequency gives:
\[ \nu = \frac{E}{h} \]

3. **Substitute the Values**:
We know the value of Planck's constant:
\[ h = 6.63 \times 10^{-34} \text{ J s} \]
Now substituting the values into the frequency equation:
\[ \nu = \frac{1.76 \times 10^{-18} \text{ J}}{6.63 \times 10^{-34} \text{ J s}} \]

4. **Calculate the Frequency**:
Performing the division:
\[ \nu = \frac{1.76}{6.63} \times 10^{15} \text{ Hz} \approx 2.65 \times 10^{15} \text{ Hz} \]

5. **Determine the Region of Electromagnetic Radiation**:
The frequency calculated (approximately \(2.65 \times 10^{15} \text{ Hz}\)) falls within the ultraviolet region of the electromagnetic spectrum.

### Conclusion:
The appropriate electromagnetic radiation required to achieve the dissociation of a carbon monoxide molecule into carbon and oxygen atoms is in the ultraviolet region.
