Option A. Powdered zinc with a high concentration of HCL at a higher temperature will have a faster rate of reaction.

Zn(s) + HCl(aq)→ ZnCl (aq) +H2 (g) the combination that will affect the rate of reaction is

Temperature, concentration and surface area (answer A)

If Zn(s) is broken into powder the surface area increases leading to speeding up the rate of reaction. When the concentration of the of dissolved reactant is increased the rate of reaction increases. An increase in temperature led to increase in movement of particle and more collision happen hence the rate of reaction is increased.
