Lithium and potassium are metals belonging to Group I of the Periodic Table. Lithium has a melting point of $181\,^\circ\text{C}$ and a density of $0.53\,\text{g cm}^{-3}$. Which row gives the melting point and density of potassium?
- Amelting point less than $181\,^\circ\text{C}$, density less than $0.53\,\text{g cm}^{-3}$
- Bmelting point less than $181\,^\circ\text{C}$, density greater than $0.53\,\text{g cm}^{-3}$
- Cmelting point greater than $181\,^\circ\text{C}$, density less than $0.53\,\text{g cm}^{-3}$
- Dmelting point greater than $181\,^\circ\text{C}$, density greater than $0.53\,\text{g cm}^{-3}$
