Regex for splitting the content from open ai response

How to use regex to split the response which is given by open ai api…response contains questions and the options in the below format and i want to display only the questions in the text box and their corresponding options in the radio button
Format: Question 1: What must every sentence include to be complete? & Option 1: “a subject and a predicate” $
Option 2: “a noun and a verb” $
Option 3: “a topic sentence and a detail sentence” $
Option 4: “a capital letter and ending punctuation”

Suggest if there is any other way possible if not in regex

Split by & for question and then by $ for each option
