Solution

The correct option is C Decreases
Across a period, the effective nuclear charge acting on the valence shell electrons increases, so, the tendency to lose electrons will decrease. Therefore, these electrons can not be lost easily. Hence, the metallic character decreases across a period.
Metal oxides are basic in nature, hence metallic character decreases across a period basic nature of oxides will also decrease.
