System inputs and outputs are produced at the end of the: a. systems analysis phase of the sdlc. b. systems planning and selection phase of the sdlc. c. systems design phase of the sdlc. d. systems implementation and operation phase of the sdlc. logic modeling stage.

A) systems analysis phase of the SDLC.

Explanation:

In accordance with system development life cycle(SDLC) , analysis phase is the stage where all the requirement and materials for the system are collected and ordered.The requirements are in the form of input and output which are extracted and documented to provide clear vision of outcome.

Other options are incorrect because design phase is for designing the format ans structure of system through input components. Planning and selection stage is making scheme through opting correct requirement for system.Implementation and operation phase is the stage of implementing the components on system structure to make them perform their respective tasks. Logic modelling level is defining inputs , components, outputs in logical manner so that they provide desired result operating.Thus, the correct operation is option(A).
