The correct answer is:
X-ray
Given radiation has $14.4 \mathrm{keV}$ energy, so it is within the energy range for X-rays which is between $100 \mathrm{eV}$ to $100 \mathrm{keV}$.
The wavelength of given radiation,
$\begin{aligned}
\lambda & =\frac{h c}{E} \text { joule }=\frac{6.64 \times 10^{-34} \times 3 \times 10^8}{14.4 \times 10^3 \times 1.6 \times 10^{-19}} \text { volt } \\
& =0.86 Å
\end{aligned}$
X-rays have wavelength range between 0.1 A to $1 Å$.
