In the periodic table, the basic character of oxides;
A
increases from left to right and decreases from top to bottom.
B
decreases from right to left and increases from top to bottom.
C
decreases from left to right and increases from top to bottom.
D
decreases from left to right and increases from bottom to top.
Explanation
As the electronegativity of element increases, acidic character of oxides increases. So, in a group, basic nature increases on moving down and decreases along a period.
