Strategy:
 Melting points in metals depend on the strength of metallic bonding, which correlates with the number of valence electrons and atomic size. Transition metals generally have significantly higher melting points than alkali metals or post-transition metals.

Step 1: Evaluate the options
- Gallium (Ga): Melts at  (very low).
- Mercury (Hg): Liquid at room temperature ().
- Cesium (Cs): Alkali metal, melts at .
- Silver (Ag): Transition metal with strong metallic lattice. Its melting point
