Lead will replace silver.

Reason: Pb is more reactive (higher in the metal activity series) and has a more negative reduction potential than Ag+, so solid lead will oxidize and reduce Ag+.

Example reaction:
Pb(s) + 2 AgNO3(aq) → Pb(NO3)2(aq) + 2 Ag(s)

(E°cell ≈ 0.80 − (−0.13) = +0.93 V, so the reaction is spontaneous.)
