Final answer:
The Ontological argument is the philosophical discussion that focuses on the ontological aspects and basic perfections about God and biblical theistic beliefs, positing that the concept of the greatest being inherently includes its existence.
Step-by-step explanation:
The philosophical argument that often discusses the ontological and basic perfections about God and biblical theistic beliefs is the c) Ontological argument. This argument, proposed by Anselm, is an a priori argument which reasons the necessity of God's existence without considering the physical universe. Anselm's argument approaches the concept of God itself, positing that the very idea of the greatest being implies its existence, as existence is a perfection and the greatest possible being cannot lack any perfection.
The philosophical argument that often discusses the ontological and basic perfections about God and biblical theistic beliefs is the Ontological argument. This argument is a priori, meaning it is based on reasoning alone and does not consider the existence of the physical universe. It focuses on the idea of God alone, examining the concept of necessary existence.
