-Login to WordPress Admin > Users > Your Profile.
-Leave the checkbox “Disable the visual editor when writing” unchecked i.e you should enable visual editor when writing.

Any attempt to Save the question without selecting a correct answer will display a message
“No answer deposited!”, if you do not put any answer or
“Correct answer was not selected!”, if you put answers but did not select the right/correct answer.
– Click on Save button, and check the answer you selected. The correct answer you selected will remain selected/saved.
– If you go back to the overview screen and edit any question, the correct answer is also saved.
THIS TOTALLY SOLVES THE PROBLEM!
