Answer:

Join

Explanation:

Five basic set operators in relational algebra are as follows:

  • Selection - tuple selection
  • Projection - extract columns
  • Cartesian product - cross product of relations
  • Set union - union of two relations
  • Set difference - minus operation on two relations

As we can see, Join is not part of the basic set operations but it is implemented using the Cartesian Product operator.

In the given question option numbers is defined, so the explanation to this question  as follows:

The volume of an element holds one mole at high temperatures. The nuclear mass is usually indicated by mole: cc/mol in the \ cm^3. It is also known as a quantity, in which the same molecule was the measured values based on atomic mass as well as the thickness of both, and certain alternatives were wrong which can be explained as follows:

  • atom doesn't fill the protons, neutrons, and electrons.
  • It can't revolve with outside atoms and electrons.
