The correct choice is (b) Network entry
Explanation: There are four types of resources in an application cache which are 1) Master Entries 2) Explicit Entries 3) Network Entries 4) Fallback Entries. Resources are explicitly listed in the application’s cache manifest file by the explicit entry. Fallback entry provides fallback entries in the application’s manifest file. Master entries are the resources added to the cache. Network entry executes and load scripts and code from the server, not from the cache. Syntax is
CACHE MANIFEST
NETWORK:
/api
Resources are explicitly listed in a cache in explicit entries. When attempt to load fails fallback entry is used.
