Mutations that result in a microorganism becoming susceptible (sensitive) to an antibiotic would be isolation through which
process:
a. Selection, because antibiotic susceptibility is a deleterious trait in the presence of that antibiotic
b. Screening, because antibiotic susceptibility will not result in an observable phenotype
c. Screening, because antibiotic susceptibility is not an advantageous trait in the presence of that antibiotic
d. Selection, because antibiotic susceptibility will result in an observable phenotype
