To determine the order of conductivity of the acidic solutions based on their pH values, we need to consider that lower pH values indicate higher acidity and a greater concentration of hydrogen ions (H⁺) in the solution.

The pH values provided are:

  • HA: pH 5.6
  • HB: pH 3.9
  • HC: pH 4.7

The order of acidity (and therefore conductivity, as more conductive acids dissociate more in solution) is as follows:

  1. HA (pH 5.6) - least conductive
  2. HC (pH 4.7)
  3. HB (pH 3.9) - most conductive

Thus, the order from least conductive to most conductive is: HA, HC, HB

The correct answer is: HA, HC, HB
