To determine what is happening at Step 3 regarding bacteria's response to antibiotics, it's essential to consider common scenarios in the context of antibiotic treatment. Typically, the sequence involves:
1. **Normal bacteria present before treatment** - these include both susceptible and resistant strains.
2. **Introduction of antibiotics** - this targets and kills susceptible bacteria.
3. **Survival and multiplication of resistant bacteria**, which become more prevalent as the susceptible bacteria are eliminated.
Based on this understanding, at Step 3, the most appropriate answer would be:
**a) The resistant bacteria are multiplying.**
This reflects the typical outcome of antibiotic treatment where the remaining resistant strains survive and proliferate in the environment created by antibiotic application.
