Verified by Experts
The correct answer is:
A

Statement I is false as with atomic number 17 the element has tendency to gain one electron to complete its octet. So, the most probable oxidation number is -1 .

Statement II is true. Since, halogen elements are short of one electron in their valence shell, so they have the tendency to gain electron.
