Solution

The correct option is B First Normal
A relation scheme is said to be in first normal form if the values in the domain of each attribute of the relation are atomic.

First normal form(1NF) is a property of a relation in a relational database. A relation is in first normal form if and only if the domain of each attribute contains only atomic (indivisible) values, and the value of each attribute contains only a single value from that domain.
