Best Answer Explained in Below-:

The correct answer is A: "Does not believe in God." An atheist is defined as someone who lacks belief in the existence of any deity or deities, particularly the God as understood in monotheistic religions. This position is characterized by a rejection of theistic claims and implies a skepticism towards religious doctrines that assert the existence of God.

In contrast, option B ("Believes in God") directly contradicts the definition of atheism since it implies a faith or belief in deity, which atheists explicitly do not endorse. Options C ("Hates God") and D ("Loves God") further misinterpret atheism; they suggest an emotional relationship with God that atheists, by definition, do not engage in, since they do not accept the existence of a deity to love or hate.

Understanding atheism, therefore, revolves around the absence of belief rather than a mere opposition to religion or personal feelings about God. This definition is critical in discussions about religion, belief systems, and philosophical perspectives on existence.
