Answer 1

You can fetch the product options using this code,

$_objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $_objectManager->get('\Magento\Catalog\Model\Product')->load($productId);
$customOptions = $_objectManager->get('Magento\Catalog\Model\Product\Option')->getProductOptionCollection($product);
