The earliest stage in the application's SDLC at which performance efficiency testing can be performed is during requirements analysis. At this stage, performance requirements and goals are established, providing a baseline for what needs to be tested and verified throughout the later stages of development​​.

The provided pseudo code for the Answer program shows a WHILE loop that will always execute because the condition for the loop to terminate (a >= d) is never met within the loop's body. This results in an infinite loop. Additionally, since the value of 'b' is initialized with 'a + 10' and 'a' starts from a value that is read and then set to 2, 'b' will never be equal to 12. Therefore, the 'THEN' branch of the IF statement, which includes 'print(b)', is unreachable. These are control flow anomalies because they represent logic in the code that will not function as presumably intended.

Installability testing is usually conducted during the System Testing stage of the SDLC. It typically includes testing the installation process of the software to verify that it installs correctly across various systems and configurations. This type of testing often overlaps with functionality testing to ensure all functions are available post-installation, and usability testing to ensure that the installation process is intuitive and user-friendly.

Explanation: System testing encompasses a broad spectrum of testing practices intended to validate the software in its entirety, ensuring it meets the specified requirements and is ready for operation.
