Solution

The correct option is C Decreases from left to right and increases from top to bottom
On moving along a period, the tendency to lose electrons decreases and thus, the metallic character decreases. Since the oxides of non-metals are acidic. Thus it can be said, along a period from left to right basic character decreases while on moving downward, the basic character increases due to an increase in metallic character.
