Answer:
Development & implementation phase
Explanation:
There are mainly six stages of SDLC, which are as follows:
1. Planning: Planning is the first step in app development, where the developer preplans every aspect of the software.
2. Analysis: After planning, the developer analyzes further requirements to develop the software as per planning.
3. Design: After planning and analysis, the developer makes the design which is the main architecture of the software.
4. Development & implementation: When the developer completes the design, the development phase comes in where the data is coded and recorded as per requirement and after development, implementation takes place to see if software functions properly or not.
5. Testing: Testing mainly tests the programs to check for any errors or bugs.
6. Maintenance: When the software is developed successfully, then time to time maintenance and updation of the software takes place to maintain and upgrade its working.
Hence according to the scenario, development & implementation phase is the right answer.
