Zinc is the only element among the given options that reacts spontaneously with 1.0M HCl at room temperature, as indicated by the activity series of metals. Copper, silver, and gold do not react with dilute acids due to their placement below hydrogen in the series. Therefore, the correct answer is D. Zinc.
