b. They indicate the area where pilots should aim for landing and are marked with white arrows.

Explanation:

Runway touchdown zone markings refer to the option (b). They indicate the area where pilots should aim for landing. These markings consist of groups of one, two, and three rectangular bars symmetrically disposed about the runway centerline. The bars are 150 feet (45m) long and each group is spaced 500 feet (150m) apart. Importantly, these markings provide distance information during the landing rollout, with the objective of enhancing operational safety. They do not serve to mark the beginning or end of the runway, nor they are meant to identify taxi routes on the runway.
