The Choice element has no Opt entry but it has V one.
About Opt:

(Optional) An array of options that shall be presented to the user. Each element
of the array is either a text string representing one of the available options or an
array consisting of two text strings: the option’s export value and the text that
shall be displayed as the name of the option.
If this entry is not present, no choices should be presented to the user.

and V:

The field dictionary’s V (value) entry (see Table 220) identifies the item or items currently selected in the choice
field. If the field does not allow multiple selection—that is, if the MultiSelect flag (PDF 1.4) is not set—or if
multiple selection is supported but only one item is currently selected, V is a text string representing the name
of the selected item, as given in the field dictionary’s Opt array. If multiple items are selected, V is an array of
such strings. (For items represented in the Opt array by a two-element array, the name string is the second of
the two array elements.) The default value of V is null, indicating that no item is currently selected.

In Acrobat, when disabling the readonly mode, the field is displayed as a choice widget (with the arrow on the right) and since it's a mix of a text field and a choice list (something we don't have in pure HTML), the text field value is the V entry.
