An example of modular construction is:

While an apartment building can be constructed using modular techniques, it is not inherently an example of modular construction. Apartment buildings can also be built using traditional methods, and thus this choice does not specifically define modularity, making it a less accurate option.

This choice refers to a home that serves as a display or prototype but does not inherently involve the modular construction process. A model home may showcase various construction techniques but does not explicitly indicate that it is built using modular components, thus making it an incorrect option.

A log cabin typically represents a traditional building method, where logs are used as the primary construction material. This method does not employ modular construction techniques as it focuses on individual logs and craftsmanship rather than pre-manufactured modules, making it an unsuitable example of modular construction.
