The answer to your question would more than likely be chemical energy, natural gas, and chemical energy. but I don't know what grade your in I'm in eighth if your below I know the answer. I'm pretty sure I had a question exactly like this last year but that was last year so if it's wrong sorry. I looked it up on Google to make sure

Explanation:

Given that,

The frequency of electromagnetic spectrum is $2.73\times 10^{16}\ Hz$

(A) Let the wavelength of this radiation is $\lambda$ . We know that,

$c=f\lambda\\\\\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{2.73\times 10^{16}}\\\\\lambda=1.09\times 10^{-8}\ m$

So, the wavelength of this radiation is $1.09\times 10^{-8}\ m$ .

(B) Let E is the energy associated with this radiation. Energy of an electromagnetic radiation is given by :

$E=hf$

h is Planck's constant

$E=6.63\times 10^{-34}\times 2.73\times 10^{16}\\\\E=1.8\times 10^{-17}\ J$

1 kcal = 4184 J

It means,

$1.8\times 10^{-17}\ J=\dfrac{1}{4184}\times 1.8\times 10^{-17}\\\\=4.3\times 10^{-21}\ \text{kcal}$

Hence, this is the required solution.
