What does "ominous" imply?

The term "ominous" conveys a sense of foreboding or a hint that something negative or threatening may occur. It often describes conditions or signs that suggest danger or misfortune is looming. When something is characterized as ominous, it evokes an unsettling feeling, making people cautious or anxious about what may follow. This aligns perfectly with the choice that indicates it signals something evil is about to happen, as "ominous" is frequently used in literature and conversation to describe dark clouds, eerie sounds, or any situation that builds tension or anticipates a bad event.

Other options suggest positive outcomes or neutrality, which do not capture the inherently menacing nuance of "ominous." Thus, the interpretation of "ominous" as a forewarning of evil or trouble makes it the most accurate choice.
