Quat solutions are commonly used as sanitizers in the foodservice industry to kill bacteria and other harmful microorganisms on surfaces and equipment. The strength of a quat solution is measured in parts per million (ppm), which represents the concentration of active ingredients in the solution. The minimum strength recommended for sanitizing implements is 11000, or 200 ppm.

Option A (1:500) and D (1:1500) are incorrect as they are either too strong or too weak for effective sanitation. A solution that is too strong can be harmful and potentially damage equipment, while a solution that is too weak may not effectively kill all bacteria and other microorganisms.

Option B (1:200) is incorrect as it is much stronger than the recommended minimum strength. This concentration may be suitable for disinfecting heavily soiled surfaces, but is not necessary for regular sanitation of implements. Therefore, option C (1:1000) is the most appropriate and effective choice for ensuring proper sanitation.
