The correct answer is C: 3rd Ionisation energy.

Here's why:

1. Ionisation energy is the energy required to remove an electron from an atom or ion.

2. The 1st Ionisation energy refers to the energy needed to remove the first electron from an atom.

3. The 2nd Ionisation energy refers to the energy needed to remove the second electron from an atom.

4. Therefore, the 3rd Ionisation energy refers to the energy needed to remove a third electron from an atom.

5. In this case, we're talking about a dipositive cation, which means it has already lost two electrons. So, the energy required to remove another electron (the third one in this case) would be referred to as the 3rd Ionisation energy.
