Explanation:

Bacteria, especially pathogenic ones relevant in medical facilities, typically multiply best in moderate temperature ranges. The range of \(20^\circ\text{C}\) to \(45^\circ\text{C}\) is optimal for many bacteria's metabolic activities and growth. \(0^\circ\text{C}\) to \(100^\circ\text{C}\) is too broad (includes freezing and boiling extremes), \(10^\circ\text{C}\) to \(30^\circ\text{C}\) and \(10^\circ\text{C}\) to \(40^\circ\text{C}\) don't cover the upper end of optimal growth for many bacteria as well as \(20^\circ\text{C}\) to \(45^\circ\text{C}\) does.

Answer:

\(20^\circ\text{C}\) to \(45^\circ\text{C}\) (the option with this temperature range, assuming the second option is \(20^\circ\text{C}\) to \(45^\circ\text{C}\) as per typical bacterial growth knowledge)
