Convection is the transfer of heat in a fluid (which can be a liquid or gas) through the movement of its particles. A fluid near a heat source will get heated, causing it to rise and exchange place with the cooler, denser fluid.
Explanation:
Energy transfer by convection is primarily restricted to both liquids and gases, which are both classified as fluids. Hence, the correct answer is D. Fluids.
Convection refers to heat transfer in a gas or liquid by the circulation of currents from one region to another. This happens when a fluid near a heat source gets heated, its particles move faster and spread apart, causing the fluid to become less dense. As a result, the warmer, less dense fluid rises, and the cooler, denser fluid sinks. The continuous movement of fluid in this way creates what we call a convection current, which results in the transfer of energy.

Final answer:
Among B, C, F, Li, and Na, Fluorine (F) has the least metallic character as it is the most nonmetallic element on the Periodic Table. This is related to its high electronegativity, which is a characteristic of nonmetals.
Explanation:
The element with the least metallic character out of B, C, F, Li, or Na would be Fluorine (F). In the Periodic Table, metallic character decreases as you move across a period from left to right and increases as you go down a group. Fluorine is located at the top right corner of the Periodic Table, which makes it the most nonmetallic element not only among B, C, F, Li and Na, but also in the entire Periodic Table.
This is because Fluorine has the highest electronegativity, meaning it has a high propensity to attract electrons in a bond. This is a property of nonmetals, in contrast to metals which tend to lose electrons.
