Why does Greenhalgh $(2021)$ ultimately argue for using a meta$-$philosophical approach to evaluate moral uncertainties?

Group of answer choices

To ensure ethical decision$-$making is consistent and in alignment with appropriate moral codes.

To be reflexive about why we are choosing a particular framework for evaluating a moral uncertainty rather than using whichever framework best suits our interests and desires.

To have an ethical toolbox of frameworks that offer different ways to justify our ethical decision$-$making.

To avoid reliance upon one universal approach for solving all moral uncertainties.
