Answer 1

You can try with this event it's working for me.

Event name :: adminhtml_catalog_product_attribute_edit_frontend_prepare_form

In observer you can get attribute detail and option like below

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $attributeData = $observer->getEvent()->getAttribute()->getData(); /* for attribut data */
$optionData = $observer->getEvent()->getAttribute()->getSource()->getAllOptions();
        echo '<pre>';print_r(attributeData);exit();
        echo '<pre>';print_r($optionData);exit();
        return $this;
    }
