Statement 1: The selector input[ng-reflect-name="labelField1"] is a standard CSS attribute selector. It correctly targets the <input> element because the HTML snippet explicitly contains the attribute ng-reflect-name="labelField1".
Statement 2: This selector uses the :has() and :contains() pseudo-classes (supported by most modern automation engines and jQuery). It identifies the div that contains a label with the text "Field1" and then selects the direct child input. This correctly maps to the hierarchy in the provided HTML.
Statement 3: The JavaScript snippet uses jQuery syntax ($). The selector div:contains('Field1') > input successfully identifies the target input field, and the .val() method is the standard jQuery function to assign a value to an input element.
