The total number of groups in the Modern Periodic Table is 18.
Explanation:
The Modern Periodic Table is arranged based on increasing atomic numbers and properties of elements.
The vertical columns in the periodic table are called groups.
There are 18 groups in the Modern Periodic Table. Each group contains elements that have similar properties due to having the same number of valence electrons (except for transition metals, where the pattern is more complex).
Thus, the correct answer is:
C. 18.
