Answer: Option (A) is the correct answer.
Explanation:
Non-metals are the species which readily accept an electron in order to gain stability.
And, when we move from left to right in a periodic table then there occurs a decrease in size of their atomic size.
Hence, smaller is the size of non-metal more will be its ability to attract the electrons towards itself. As nucleus of a small atom will show strong force of attraction between the protons and electrons.
Therefore, reactivity of non-metals increases on moving from left to right in a period.
Thus, we can conclude that for nonmetals, reactivity increases as you go from left to right in a period.
