What are the three parts of a trigger in Tag Manager?

In Google Tag Manager, a trigger determines when a tag fires. The three essential parts of a trigger are variables, operators, and values. A variable represents a dynamic piece of information, such as a URL, a click ID, or a custom data layer variable. An operator defines the relationship between the variable and the value (e.g., "equals," "contains," "starts with"). The value is the specific data point the variable is being compared against. For example, a trigger might be configured as "Page URL" (variable) "contains" (operator) "thank-you.html" (value). The incorrect options include elements that are not direct components of a trigger's condition logic. "Tags" are fired by triggers, not part of their definition. The "data layer" is where data is stored, and "the push method" is how data is added to it, but neither are direct parts of a trigger's conditional structure.
