Styling choice labels?

How can we do this for the labels from the choice list? The above solution did nothing to the display of choices

eg: Tiger (Panthera tigris) or even Tiger (Panthera tigris) simply shows as Tiger (Panthera tigris) and not as Tiger (Panthera tigris)

(I am using ODK collect 4.2 version)

Is there a reason you are not using the latest version of Collect - v2023.2.4?

Styling should work on choices - although just in Collect, not in Enketo.

+-----------+------+---------------------------------------------+
| list name | name |                    label                    |
+-----------+------+---------------------------------------------+
| options   | a    | is this _italic_ text?                      |
| options   | b    | is this **bold** text?                      |
| options   | c    | is this <span style="color:red">red</span>? |
+-----------+------+---------------------------------------------+

I have tried all the variations of italics as mentioned, yet continue to face the same issue.

I am using the older version to keep using Google sheets

Unfortunately, if that's the case then I am guessing it is a bug in the outdated version of Collect.

This works nicely in Collect.
Though in Enketo it does not, right?

Or am I wrong in my coding?

You're correct that there are differences between how Enketo and Collect handle the styling and not everything works on both. When the new web forms are released, it should solve these issues:
