Alexander Fleming. It is a discovery.

B This scientist was shocked when he was observing some molds on the dish of bacteria . What did he find?

"Surprisingly, he saw not only the mold growing on the staphylococci bacteria, but a clear zone around the mold. The Penicillium mold, the precursor to penicillin, was dissolving the deadly staphylococci bacteria. – quote from the source named below. 

C who made the first penicllin drug? Is the drug a discovery or an invention?

A team of Oxford research scientists led by Australian Howard Florey and including Ernst Boris Chain and Norman Heatley devised a method of mass-producing the drug.You can call it an invention because the drug is synthetic penicillins. It does not occur naturally.
