A common characteristic of a hollow core brick is that it can enhance insulation properties. The design of hollow core bricks incorporates air spaces within the brick, which act as thermal insulators. These air pockets reduce the overall thermal conductivity of the material compared to solid bricks, helping to maintain temperatures and improve energy efficiency in buildings. This characteristic makes hollow core bricks particularly valuable in construction for creating energy-efficient structures.

In this context, other characteristics that may appear in comparison are less relevant. For instance, hollow core bricks are typically not heavier than standard bricks due to the voids within them, which actually make them lighter. They also tend to have lower thermal conductivity compared to solid bricks, making option B less applicable. While there may be cases where hollow core bricks can be more expensive, this is not inherently a defining characteristic of their design or function, thus making option D less relevant to their primary purpose.
