Which of the following properties increases across a period

A) Reducing property(ability to loose electron) decreases on moving along a period from left to right due to decrease in size

B) Atomic size decreases on moving along a period from left to right due to increase in effective nuclear charge.

C) Acidic nature of oxides increases across a period as nonmetallic nature increases.

D) Metallic character(ability to loose electron) decreases on moving along a period from left to right due to decrease in size and increase in effective nuclear charge.
