Q3 Single choice

You have been asked to determine a TAS for a new release of a SUT, test should be automated wherever.
The new release will consist of 5 new interfaces and an amendment to 3 existing interfaces. The new and amended interface will be deliver incrementally in 3 sprints, each lasting 2 weeks.

What would be the BEST Test Automation Solution (TAS) design in this scenario?

A
Automate tests at both Component and System Level. Only do this automation once every interface has been fully developed or amended and manual testing has completed successfully.
B
Automate tests at one level only, System level. Use only the newly developed interfaces and do not
create any customized interfaces/test hooks.
C
Automate the tests at two levels, Component and System level. Create customized hooks at Component level for interface not yet developed or amended. Only use the newly developed or amended interfaces to test at System level.
D
Automate a test at once level, component level, Create customized interface/test hooks for this level where the interface has not yet been developed or amended.
