The standard oxidation potential value of Li is greater than that of K. But K is more reactive towardds water than Li, because

Options

A. The melting point of K is less than Li and the heat of reaction is sufficient to make it melt. So the molten metal spreads out, and expose a large surface to the water.
B. The melting point of Li is less than K and the heat of reaction is sufficient to make it melt. So the molten metal spreads out, and expose a larger surface to the water.
C. The boiling point of K is more than Li and the heat of reaction is sufficient to make it melt. So the molten metal spreads out, and expose a larger surface to the water.
D. All the above are correct
