Assertion: Gallium is a liquid at room temperature whereas aluminum is solid.
Reason: Gallium has weaker metallic bonding than aluminum, leading to lower melting and boiling points.
Both Assertion and Reason are true, and the Reason is the correct explanation of the Assertion.
Both Assertion and Reason are true, but Reason is not the correct explanation of the Assertion.

Assertion is false, but Reason is true
Gallium does have weaker metallic bonding than aluminium, leading to lower melting and boiling points, which is the Reason. However, the Assertion that gallium is a liquid at room temperature whereas aluminium is solid is not explained by the Reason, as the melting point of gallium is lower than at room temperature while the melting point of aluminium is higher. Gallium is a metal that has a low melting point of just 29.76°C, which is lower than room temperature, while aluminium has a melting point of 660.32°C
