B. `1s^(2)2s^(2) 2p^(6)3s^1`
C. `1s^(2) 2s^(2)2p^(6) 3s^2`
D. `1s^(2) 2s^(2) 2p^(1) `

Explanation

To determine which electronic configuration is associated with the biggest jump between the 2nd and 3rd ionization energy (IE), we need to analyze the configurations provided and their stability after the removal of electrons.

### Step-by-Step Solution:

1. **Understand Ionization Energy (IE)**:
- Ionization energy is the energy required to remove an electron from an atom or ion. The first ionization energy (IE1) is the energy needed to remove the first electron, the second ionization energy (IE2) is for the second electron, and so on.
- A significant jump in ionization energy typically occurs when an electron is removed from a stable electron configuration, such as a noble gas configuration.

2. **Analyze the Given Configurations**:
- We need to look at each option and see how the electron removal affects the stability of the resulting ion.

3. **Option 1**: Configuration is not specified, but we know it does not attain noble gas configuration after removing two electrons.
- This means that there is no significant stability achieved after the removal of two electrons, so we can expect a relatively small jump between IE2 and IE3.

4. **Option 2**: Configuration is such that after removing one electron, it attains noble gas configuration.
- If the configuration reaches a noble gas state after the first removal, the second removal would not require significantly more energy, leading to a smaller jump between IE2 and IE3.

5. **Option 3**: Configuration is 1s² 2s² 2p⁶ 3s².
- After removing the first electron (IE1), the configuration becomes 1s² 2s² 2p⁶ 3s¹. This configuration is still not a noble gas configuration.
- After removing the second electron (IE2), the configuration becomes 1s² 2s² 2p⁶, which is a noble gas configuration (Neon).
- The removal of the third electron (IE3) from a noble gas configuration requires a significantly higher amount of energy due to the stability of the noble gas configuration.

6. **Conclusion**:
- The biggest jump in ionization energy occurs in Option 3, where the transition from the second to the third ionization energy involves removing an electron from a stable noble gas configuration.

### Final Answer:
The configuration associated with the biggest jump between the 2nd and 3rd ionization energy is **Option 3: 1s² 2s² 2p⁶ 3s²**.
