Selected Answer: D
It's D. P151: "First normal form (1NF): Ensures each entity has a valid primary key, and every attribute depends on the primary key; removes repeating groups, and ensures each attribute is atomic (not multi-valued).1NF includes the resolution of many-to-many relationships with an additional entity often called an associative entity."
