For the Matrix Radio field, to ensure that each answer option is selected only once within the entire matrix, enable Limit to one response per Answer column option under Validation. This helps the respondents to make distinct choices.

For example, if a matrix has columns for High Priority, Medium Priority, and Low Priority, enabling Limit to one response per Answer column would prevent a user from choosing High Priority for multiple questions.
