In above question there is two-term is used first is , for ductile and second is conservative .
For ductile material two possibilities MSST and MDET. But MSST conservative is most because it has hexagonal form and MDET have an ellipse in charm curve.

In the above 2 conversations, they missed one point that is in question.

It is asked to find most conservative value so the answer is maximum normal stress theory.
