Which of the following is a typical application for stranded wire in marine use?

Stranded wire is commonly used in marine applications due to its flexibility and durability. In particular, it is ideal for installation where movement or vibration is expected, such as in the case of underwater lights. These lights can be installed in locations that may require bending and twisting of the wire to accommodate the mounting and positioning of the fixtures.

Stranded wire's construction, which consists of multiple thin strands of wire twisted together, allows it to bend easily without breaking, making it well-suited for environments that may subject the wiring to stress or movement, such as in connections to underwater lights. In contrast, other options such as connecting battery terminals typically utilize solid wire for stability under fixed conditions, while permanent fixtures may not demand the flexibility that stranded wire offers. High-demand systems may also require thicker, solid wire to handle increased currents without overheating.
