Solution

The correct option is C Assertion is correct but reason is incorrect
The element has a tendency to lose the electron(s) to attain the stable configuration. For example, $N a$ atom with one valence electron will lose one electron to form a stable electronic configuration of neon. This will complete its octet.
Ionization enthalpy is the energy required to remove an electron from an isolated gaseous atom in its ground state. Energy is required to overcome the attraction between nucleus and valence electron.
Hence, assertion is correct but reason is incorrect.
