(C) The atomic number of silver $(Ag)$ is $47$. Following the Aufbau principle and considering the stability of the half-filled or fully-filled $d$-orbitals,the electron from the $5s$ orbital shifts to the $4d$ orbital to make it fully filled. Thus,the electronic configuration is $[Kr] 4d^{10} 5s^1$.
