C
1-b, 2-c, 3-a
D
1-a, 2-c, 3-b
Explanation: 

Detailed explanation-1: -Explanation: A waterfall model is also known as linear sequential model. This model gives a systematic, sequential approach to system development that begins at a systematic level and progresses through communication, planning, analysis, modeling, testing, deployment and maintenance. 2.

Detailed explanation-2: -A Waterfall model is neither Incremental nor Iterative because it develops the whole system at once, without any increments or iterations.

Detailed explanation-3: -Winston Royce introduced the Waterfall Model in 1970.This model has five phases: Requirements analysis and specification, design, implementation, and unit testing, integration and system testing, and operation and maintenance.

Detailed explanation-4: -The waterfall model is a linear, sequential approach to the software development lifecycle (SDLC) that is popular in software engineering and product development. The waterfall model uses a logical progression of SDLC steps for a project, similar to the direction water flows over the edge of a cliff.
