What are the two primary components of the hood's lock assembly?

The two primary components of a hood's lock assembly are the safety catch and the latch. The safety catch serves as a backup mechanism that prevents the hood from opening while driving should the primary latch fail. The latch is the component that secures the hood closed. Together, these two components ensure both the security of the hood during operation and safe access when necessary.

The other options contain components that may play roles in the broader functioning of a vehicle's hood system but do not directly represent the primary components of the hood's lock assembly. For instance, while a release cable may be involved in the operation, it is not one of the core components of the lock assembly itself. Similarly, a pop-up spring serves a different purpose related to hood safety and aesthetics rather than being a primary component of the lock mechanism.
