What does the continued steady flow from the grassy hillside spring suggest about groundwater's role in the water cycle during dry periods?

A spring flowing steadily during a dry period shows that stored groundwater can continue feeding surface water even when there is no recent rainfall. This is groundwater discharge, so the observation supports choice A. It does not show that groundwater is unaffected by drought, only that stored water can sustain flow for a time.
