Explanation by: Admin

Gallium (Ga) is a metal that remains in a liquid state at slightly above room temperature (melting point: 29.76°C or 85.57°F). It can melt in the palm of your hand and is used in electronics and semiconductors.

Other Options Explained:

(A) Sodium – A soft metal but solid at room temperature (melting point: 97.8°C).

(B) Silicon – A metalloid and solid at room temperature (melting point: 1414°C).

(D) Radium – A radioactive metal that is solid at room temperature (melting point: 700°C).


Thus, the correct answer is (C) Gallium.
