Implementation

magento/magento2/blob/ffea3cd/app/code/Magento/Config/Model/Config/Structure/Element/Field.php#L352-L369


/**
 * Retrieve static options or source model option list
 *
 * @return array
 */
public function getOptions()
{
    if (isset($this->_data['source_model'])) {
        $sourceModel = $this->_data['source_model'];
        $optionArray = $this->_getOptionsFromSourceModel($sourceModel);
        return $optionArray;
    } elseif (isset($this->_data['options']) && isset($this->_data['options']['option'])) {
        $options = $this->_data['options']['option'];
        $options = $this->_getStaticOptions($options);
        return $options;
    }
    return [];
}

The single usage:

\Magento\Config\Block\System\Config\Form::_initElement()

github.com

magento/magento2/blob/ffea3cd/app/code/Magento/Config/Block/System/Config/Form.php#L375-L377


if ($field->hasOptions()) {
    $formField->setValues($field->getOptions());
}

Details: How are the options set to a select/multiselect form element?
