To determine which of the given temperatures in Kelvin is equivalent to 5°C, we need to convert the Celsius temperature to Kelvin. The formula to convert Celsius to Kelvin is:

[tex]\[ K = C + 273.15 \][/tex]

Where:
- [tex]\( K \)[/tex] is the temperature in Kelvin
- [tex]\( C \)[/tex] is the temperature in Celsius

Let's follow the steps to find the Kelvin equivalent of 5°C:

1. Start with the given temperature in Celsius: 5°C.
2. Apply the conversion formula:

[tex]\[ K = 5 + 273.15 \][/tex]

3. Perform the addition:

[tex]\[ K = 278.15 \][/tex]

So, the Kelvin equivalent of 5°C is 278.15 K.

Next, we compare this result with the given choices:

- Choice A: 278 K
- Choice B: 41 K
- Choice C: 0 K
- Choice D: 465 K

Upon comparison, none of the choices exactly match 278.15 K. So, the correct answer is:

[tex]\[ \boxed{\text{None}} \][/tex]

Thus, none of the given options represent the temperature equivalent to 5°C exactly.
