What is the primary design of Board and Batten siding?

The primary design of Board and Batten siding is characterized by wide boards that are attached vertically, leaving small gaps between them, which are then covered by narrow batten strips. This classic method not only provides a distinctive visual appeal but also allows for the natural expansion and contraction of the wood, which is important for durability and weather resistance. The battens help to seal any gaps and prevent water intrusion, enhancing the overall effectiveness of the siding while contributing to its aesthetic charm.

The other choices do not accurately represent the Board and Batten style. For instance, horizontal installation or no gaps does not align with the classic vertical design accompanied by battens, which is the essence of this siding method.
