Hello, I want to use LaTex in questions and options. How …

Hi Satish,
there is no LaTex formatting, but you can use just good old fashioned HTML to do most formatting you need.

For example, to make text bold, you can use the strong tag. em for italics, sub and sup for sub or superscript etc.

As for answer explantions: that’s already built in! When editing a quiz, select the “extra” tab and you will see where you can display some extra text if the user gets the question wrong. You can also enable the quiz setting “Always Show Incorrect Answer Text” under the Marking tab if you want this extra text to show even if the user gets the question correct.
