Answer: Option (B) is the correct answer.
Explanation:
Elements of a group represent similar chemical properties because they contain same number of valence electrons which determines their reactivity.
Hence, elements of a group have same chemical nature or property.
A group is represented by a vertical column in a periodic table.
On the other hand, a period is represented by a horizontal line.
Thus, we can conclude that a column contains elements with similar properties in the periodic table.

<h3>What is thermal adaptation?</h3>
The ability of a body to adjust to temperature is called thermal adaptation. Mammals are the animals who can adjust the temperature of their body.
The reptiles are not able to adjust their body temperature, because they are poikilothermic. They have to take the help of outer environment to adjust their body temperature.
Thus, when you put one hand in ice water and the other in warm water, the hand in warm water will feel the room temp water cooler, and the hand in cold water feel room temperature water warmer.
