Eye Let $mathcal{X}$ be an additive full subcategory of an abelian category.It is a classical fact that if $mathcal{X}$ is contravariantly finite, then the category $mathsf {mod},mathcal{X}$ of finitely presented right $mathcal{X}$-modules is abelian.In this paper, we consider the question asking when the converse holds true for a resolving subcategory of the category of finitely Diffuser Oil generated modules over a commutative noetherian henselian local ring.We give both affirmative answers and negative answers to this question.
