Final answer:
The boundary at around 40°N latitude and 0° longitude is a transform boundary, where tectonic plates slide sideways past each other. The correct answer is option c.
Step-by-step explanation:
The boundary located at around 40°N latitude and 0° longitude is a transform boundary. Transform plate boundaries are places where tectonic plates slide sideways past each other.
The most notable example of a transform boundary is the San Andreas Fault in California. At these boundaries, earthquakes are common due to the friction between the sliding plates.
Unlike divergent boundaries where plates move apart and convergent boundaries where plates move towards each other, transform boundaries do not typically create significant topography such as mountain ranges or deep ocean trenches.
