Answer: Option (B) is the correct answer.
Step-by-step explanation:
Elements of same group tend to show similar chemical properties because elements of same group show same number of valence electrons.
Therefore, they have similar chemical properties.
For example, nitrogen and phosphorous are both group 15 elements and they show similar chemical properties.
Thus, we can conclude that because they are in the same family, we can predict about these elements that they are chemically reactive in a similar way.
