c. Only govern pedestrians

b. Must be followed

Explanation:

Traffic signs are usually on the side of a road at a park to show the right direction to motorists, cyclists or pedestrians. A large number of these traffic signs are influenced by international regulations to achieve uniformity and generalisation of the meaning of the traffic signs. At a private parking lot, traffic signs must be followed to reduce the rate of occurrence of unexpected events which may lead to injuries or even death. Furthermore, the traffic signs ensure orderliness and free flow of traffic at the lot. So it is very important to follow traffic signs appropriately when at a park, or on the road.
