He found a lucrative assignment.

good
profitable
excellent
significant

The correct answer is B.

A lucrative assignment is one that is profitable or pays well. It is an assignment that is likely to bring in a lot of money.

The other options are not as accurate descriptions of a lucrative assignment.

  • A good assignment is one that is enjoyable or satisfying.
  • An excellent assignment is one that is of the highest quality or standard.
  • A significant assignment is one that is important or has a major impact.

While these assignments may be all of these things, they are not necessarily profitable or well-paying.
