What are the logic levels of test points A, B, and C if A is low, B is high, and C is high?

The logic levels describe the binary states of certain points in a circuit, where "low" typically corresponds to a voltage level close to 0 volts (often represented as 0) and "high" corresponds to a higher voltage level (often represented as 1).

In this scenario, the conditions specify that point A is low, point B is high, and point C is high. Thus, the correct answer confirming these states is that A is indeed low, B is high, and C is high. This aligns perfectly with the requirements outlined in the question.

The other choices do not reflect the stated logic levels correctly. For instance, they alternatively assign different states to A, B, or C, which contradicts the specified conditions. Therefore, the choice that indicates A being low while both B and C remain high is the only accurate representation of the given conditions.
