Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R).$

Assertion $(A) :$ Metallic character decreases and non-metallic character increases on moving from left to right in a period.

Reason $(R)$ $:$ It is due to increase in ionisation enthalpy and decrease in electron gain enthalpy, when one moves from left to right in a period.

In the light of the above statements, choose the most appropriate answer from the options given below :
