                        "values"        => $values
                    ),
                    array(
                        "sort_order"    => 2,
                        "title"         => "Multiple Option",
                        "price_type"    => "fixed",
                        "price"         => "",
                        "type"          => "multiple",
                        "values"        => $values,
                        "is_require"    => 0
                    )
                );
         
        foreach ($options as $arrayOption) {
            $product->setHasOptions(1);
            $product->getResource()->save($product);
            $option = $objectManager->create('\Magento\Catalog\Model\Product\Option')
                    ->setProductId($productId)
                    ->setStoreId($product->getStoreId())
                    ->addData($arrayOption);
            $option->save();
            $product->addOption($option);
        }

In the code above,

$values is an array to hold the values for the select type custom option, and,

$options is an array to hold multiple custom options

When you execute the above code, the custom options of types: field, drop down and multi-select will be created in your product.
