The wages of sin ____ death.

In the biblical phrase “The wages of sin ____ death,” “is” is correct because “wages” is treated as a singular noun, meaning the consequence or reward of sin. In English, singular subjects take singular verbs, and “is” aligns with the phrase’s traditional wording. Options B (plural), C (past singular), and D (past plural) do not fit the grammatical or contextual structure, making A the correct choice.
