Correct answer
Explanation
In QTP, block commenting can be done using Ctrl+M to comment out multiple selected lines of code. This shortcut adds comment markers to all selected lines simultaneously. Ctrl+T is typically used for other purposes (like merging), Ctrl+J is not a standard commenting shortcut, and 'None' is incorrect.
