Answer : The correct option is, (A) have similar chemical properties.

Explanation :

In a periodic table, the elements in horizontal rows known as periods and vertical columns known as groups.

In periodic table, elements having similar properties lies in the same vertical columns or groups because all the elements had same number of valence electrons.

or,

The elements have similar characteristics or similar chemical properties when they are belong to the same family or group this means that when they are placed in the same column of the periodic table.

Hence, the correct option is, (A) have similar chemical properties.
