Liquids around room temperature. The only liquid elements at standard temperature and pressure are bromine (Br) and mercury $\left(Hg\right)$. Although, elements caesium (Cs), rubidium $\left(Rb\right)$, Francium $\left(Fr\right)$ and Gallium (Ga) become liquid at or just above room temperature.But Na is a solid at room temperature.
Hence options B,C & D are correct.
