Answer: Option (b) is the correct answer.

Explanation:

Chemical properties are defined as the properties which tend to chemical composition of a substance. Neutral elements with similar number of valence electrons tend to show similar chemical properties as these have same reactivity which actually affects their chemical properties.

This means that elements of the same group tend to show similar chemical properties.

For example, oxygen and sulfur atom are both group 16 elements and they have 6 valence electrons. Therefore, they show similar chemical properties.

Thus, we can conclude that a pair of O and S elements is expected to be most similar in their chemical properties.
