PLEASE I only have ten points but I need help The reactants of two chemical equations are listed.

Equation 1: PbNO3 + Mg
Equation 2: PbNO3 + KI

Based on the type of reaction, which reaction can be used to extract lead metal from lead nitrate solution? (5 points)
Equation 2, because K being more reactive, exchanges position with Pb in PbNO3
Equation 2, because K being more reactive, exchanges position with N in PbNO3
Equation 1, because Mg being more reactive, replaces N from PbNO3
Equation 1, because Mg being more reactive, replaces Pb from PbNO3
