In a one-to-one relationship, how many objects from the origin table can relate to an object in the destination table?

In a one-to-one relationship, each object in the origin table can relate to exactly one object in the destination table, and vice versa. This means that for any single object in the origin table, there can either be no corresponding objects in the destination table (0), or there is precisely one corresponding object (1). Therefore, the only valid options for relating objects in a one-to-one relationship are 0 or 1, leading to the conclusion that the correct answer is indeed 0 or 1. This concept is fundamental in relational databases where understanding how entities relate to each other helps maintain data integrity and design efficient database schemas.
