Which line in Alt Sets indicates the value for referencing a specific answer option?

The Sequence Number is fundamental in Alt Sets as it provides a unique identifier for each answer option within a survey or questionnaire. When referencing a specific answer option, the Sequence Number becomes particularly useful because it allows for accurate tracking and analysis of the responses associated with that option. Each answer can be linked back to its sequence number, enabling easy handling of the data collected from respondents.

In contrast, the other choices serve different purposes. The ALT Set identifies a group of alternative answer choices, Content Kind defines the type of content (e.g., text, number, etc.) used for the answers, and the Label provides a human-readable name for the answer option, which may not necessarily be uniquely identifiable. Thus, while each of these components plays a role in structuring survey data, the Sequence Number stands out as the definitive value needed for pinpointing specific answer options within Alt Sets.
