Let's assume that you were teaching the Gram stain to four students, and each student did one thing wrong during the Gram staining procedure, as shown below. Of the four students listed below which one will probably get a correct result (assuming everything else was done correctly) Select one: O a. One used Nigrosine with lodine as a Primary stain and mordant respectively O b. One used basic Fuchsin as a counter stain Oc One forgot the decolorizing step completely O d. One forgot to use a counter stain
