A researcher is developing a new microbial control protocol for use in a hospital setting. Which scenario best exemplifies the design and implementation of this protocol?

Select one:

a$.$ The researcher relies solely on laboratory testing results to determine the effectiveness of the new protocol, without conducting real$-$world trials in a hospital environment.

b$.$ The researcher conducts a thorough literature review to understand the factors contributing to the strengths and limitations of existing microbial control protocols before designing the new protocol.

c$.$ The researcher decides to test the new protocol only on surfaces that are easily accessible, without considering areas prone to microbial colonization and transmission.

d$.$ The researcher selects a disinfectant agent based solely on its popularity in the industry without considering its efficacy against common hospital$-$acquired pathogens.
