At a pH of 3.7:
- **Salmonella** can grow since its pH range is from 3.6 to 9.5.
- **Listeria monocytogenes** cannot grow since its pH range is from 4.2 to 9.6.
- **Escherichia coli** cannot grow since its pH range is from 4.3 to 9.0.
Therefore, the correct answer is: **b Salmonella grows. Listeria monocytogenes and Escherichia coli do not grow.**
- **Salmonella** can grow since its pH range is from 3.6 to 9.5.
- **Listeria monocytogenes** cannot grow since its pH range is from 4.2 to 9.6.
- **Escherichia coli** cannot grow since its pH range is from 4.3 to 9.0.
Therefore, the correct answer is: **b Salmonella grows. Listeria monocytogenes and Escherichia coli do not grow.**
