To answer this question, the user needs to have knowledge about exception handling in programming.

Option A is incorrect because identifying all possible erroneous inputs and managing how the application responds to them is a part of input validation. It is not the same as exception handling.

Option B is partially correct. During application execution, if some special conditions are met, then a specific subroutine 'exception handler' is called. Exception handling involves detecting errors that occur during the execution of a program and taking appropriate action to handle them. The "specific subroutine" is the exception handler which is executed when an exception is thrown.

Option C is also partially correct. Commercial runtime environments have tools that record debugging information from memory at the time of exception to provide 'root-cause' analysis information later. This tool is essential to debug errors and improve the quality of the software.

Option D is correct because all the options A, B, and C are correct explanations of exception handling.

Therefore, the answer is: D. All of the above.
