In the long or modern form of the periodic table, the element in the periodic table have been divided into four blocks, `s-p-d`-and `f`-. Each period begins with the filling of new energy shell. Two series of `f`-block elements are placed at the bottom of the periodic table.
Which of the element whose atomic numbers are given below cannot be accommodated in the present set-up of the modern periodic table?

Options

A. `109`
B. `118`
C. `120`
D. `125`

Explanation

To determine which of the given elements cannot be accommodated in the modern periodic table, we need to analyze the atomic numbers provided and their relation to the current structure of the periodic table.

### Step-by-Step Solution:

1. **Understand the Modern Periodic Table**: The modern periodic table is organized based on increasing atomic numbers, and currently, it accommodates elements with atomic numbers from 1 (Hydrogen) to 118 (Oganesson).

2. **Identify the Given Atomic Numbers**: The question mentions atomic numbers that need to be checked. Let's assume the atomic numbers given are 120, 125, and possibly others.

3. **Check the Atomic Numbers Against the Current Limit**:
- The highest atomic number currently recognized in the periodic table is 118.
- Any atomic number greater than 118 cannot be accommodated in the present setup of the periodic table.

4. **Determine Which Elements Cannot Be Accommodated**:
- If the atomic numbers provided include 120 and 125, both of these numbers exceed 118.
- Therefore, elements with atomic numbers 120 and 125 cannot be accommodated in the current periodic table.

5. **Conclusion**: The elements with atomic numbers greater than 118, such as 120 and 125, cannot be accommodated in the present setup of the modern periodic table.

### Final Answer:
The elements with atomic numbers 120 and 125 cannot be accommodated in the present setup of the modern periodic table.
