A translucent colony displaying subtle beta hemolysis is isolated from a placenta culture.  The Gram stain revealed gram-positive cocci in pairs. The microbiologist drops 3% catalase reagent onto a colony on sheep blood agar, and it produces bubbles. He then performs a Staphyloccocus latex agglutination and the suspension remains smooth. The next step is to
      a.  report the organism as Staphylococcus not S. aureus.
      b.  report the organism as Staphylococcus aureus.
      c.  repeat the catalase test due to an invalid result.
      d.  perform a thermonuclease test due to an invalid latex agglutination result.
