The correct choice for a solution commonly used for high-level disinfection (HLD) is glutaraldehyde. Glutaraldehyde is a potent chemical agent that effectively kill a wide range of microorganisms, including bacteria, viruses, and fungi, and is particularly well-suited for instruments that cannot withstand heat sterilization methods. It acts by alkylating proteins and nucleic acids, leading to cellular damage and death of the pathogens.

This solution is often used for items that require disinfection but not sterilization, particularly in settings like surgical suites or orthopedic clinics where certain heat-sensitive instruments must be adequately disinfected. It typically requires immersion time ranging from 20 to 30 minutes, offering a reliable HLD option for various medical devices.

While chlorine solutions, hydrogen peroxide, and alcohol solutions have their own disinfectant properties, they either do not meet the criteria for high-level disinfectants or are more suitable for sanitation and lower levels of disinfection. Therefore, glutaraldehyde is the preferred choice for achieving high-level disinfection effectively.
