(b)
Interpretation:
The group number of alkaline earth metal family is to be stated.
Concept introduction:
The elements in a modern periodic table are arranged in an increasing order of their atomic number. In the modern periodic table, the horizontal rows are known as periods, whereas vertical columns are known as groups. There are seven periods and eighteen groups in a modern periodic table.
