Step 1: Recall what a psychrometric chart actually plots.
A psychrometric chart is a graph of the properties of moist air at one fixed total atmospheric pressure, with dry bulb temperature on one axis and humidity ratio on the other, plus a family of curves for relative humidity, wet bulb temperature, specific volume and enthalpy.
Step 2: Check each listed property against the chart.
Dew point temperature is read by moving horizontally at constant humidity ratio until the saturation curve is reached, so it is available. Humid volume is shown directly as a set of near-diagonal specific-volume lines. Humidity, whether as humidity ratio or relative humidity, is one of the chart's basic coordinates.
Step 3: Check the triple point separately.
The triple point of water is the unique pressure-temperature condition at which ice, liquid water and vapour coexist in a pure-substance phase diagram, it belongs to thermodynamic phase-equilibrium charts, not to a constant-pressure moist-air chart, so it cannot be read off a psychrometric chart.
Step 4: Conclude.
Dew point, humid volume and humidity can all be obtained from the chart while the triple point cannot, giving (A), (C) and (D) only.
\[ \boxed{(A), (C) and (D) only.} \]
