B)starting with a liquid that contains microorganisms
C)adding antibiotics to the liquid
D)using a sterile liquid and eliminating exposure to microorganisms
E)adding carbon dioxide to the liquid

The essential step to disprove spontaneous generation in a liquid medium is to use a sterile liquid and eliminate exposure to microorganisms. This ensures that if any microorganisms do appear in the liquid, they did not arise spontaneously but instead came from outside sources. Adding nutrients (A) may support the growth of microorganisms, while starting with a liquid that already contains microorganisms (B) would not disprove spontaneous generation. Adding antibiotics (C) may kill any microorganisms present, but it would not prove that they did not arise spontaneously. Adding carbon dioxide (E) may support the growth of microorganisms but would not help disprove spontaneous generation.
