An example of modular construction is

While apartment buildings can be constructed using modular techniques, this choice is too broad and does not specifically refer to modular construction. Apartment buildings can be built using traditional methods as well, making this option less relevant as an example of modular construction compared to prefabricated housing.

A home used as a model typically implies a showcase or demonstration home that may not necessarily involve modular construction methods. This choice does not represent the modular construction process, which focuses on the assembly of prefabricated modules rather than a single model home.

Log cabins are generally constructed using traditional building methods, often involving local materials and on-site assembly. This choice does not align with the concept of modular construction, which emphasizes factory-built components rather than custom-built structures using logs.
