Answer:

The sequence of rows is significant.

Explanation:

The relational tables have the following characteristics:

Column values are of the same kind.
Each row is distinct and there are no duplicate rows.
Each column has a unique name which is used to reference that column.
The sequence of rows or columns is insignificant.

That means that if I have a table consisting of 2 rows R1 and R2 then the sequence of R1 and R2 is immaterial.
