A table is in first normal form if it does not contain ____.​
A) ​repeating groups
B) ​a foreign key

Repeating groups violate the first normal form as they contain multiple values in a single column, leading to data redundancy and inconsistency.

Foreign keys, primary keys, and alternate keys are used to enforce data integrity and relationships between tables, but they do not determine whether a table is in the first normal form.
