Final answer:
COTS software typically offers the advantages of lower development costs and an easier learning curve for users and administrators, which corresponds to answer options A and C.
Step-by-step explanation:
The advantages to using COTS (Commercial off-the-shelf) software include typically lower development costs and an easier learning curve for users and administrators. When we talk about COTS, we refer to software that is ready-made and available for sale to the general public.
Option a, that development costs are typically lower, is an advantage because the software does not require custom development from scratch. Instead, it is pre-developed and sold as a finished product, which can significantly reduce the investment needed for software acquisition.
Moreover, option c, referring to an easier learning curve for users and administrators, suggests that COTS software is often designed with user-friendliness in mind, enabling quicker onboarding and less extensive training. COTS software is not always guaranteed to integrate best with your existing IT system components, which makes option b less universally applicable. Thus, the correct answer to the advantages of using COTS software are A and C.
