During which phase of the software development process are developers MOST likely to log bugs

The answer is the testing phase.

Explanation:

Testing is the part of software development wherein developers performs test on the system to encounter bugs and possible errors before they would deploy the system. The aim of testing is to ensure that the system meets its objective (or the system perform its desired function). In any case that there is a bug or error present during the test, testers must logged it in and developers must go back to the coding stage to fix bugs they found in codes and system process. Then testers would run series of tests again to ensure that the previous errors are gone. This will be repeatedly executed until the system is down to 0 errors before it will be introduced to the clients or desired users of the system.

Normally during software development their will QC department or QC tester, who tests the software and simulates as end user operation and log bugs either MS-excel or word document there will be software for log bugs.

Explanation:

Normally end user (QC tester) take the print screen or screen shot and paste in log bugs entry software or word document and MS-excel and explains as small notes how the bug occurred so the software development can under and rectified the bugs.

Without QC tester approval on software as bugs free and installing in the client place it is high risk.
