    You should use add_option().something like this

    add_option( string $option, mixed $value = '', string $deprecated = '', string|bool $autoload = 'yes' )

    Saving the values to the wp_options table is not a normal WooCommerce behavior. WooCommerce saves product meta in wp_postmeta. There are a lot of possible downsides to storing data about specific products in wp_options. In particular, if you need to return data to the product admin editor from wp_options, you will need to labor on a method for that, as WooCommerce looks to wp_postmeta for custom meta.

    The following set of functions will create your custom input and save the value when the product is updated via WP Admin.

        /**
    * Create custom meta
    **/
    function custom_before_price() {

        $args = array(
            'id' => 'custom_price',
            'label' => __( 'Custom Price', 'cprice' ),
            'data_type' => 'text', // Let WooCommerce formats our field as price field
            'description' => __( 'Enter the text before price.', 'cprice' ),    
        );

        woocommerce_wp_text_input( $args );
    }
    add_action( 'woocommerce_product_options_general_product_data', 'custom_before_price' );


    /**
    * Save custom meta
    **/
    add_action( 'woocommerce_process_product_meta', 'save_custom_field' );
    function save_custom_field( $post_id ) {
        global $wpdb;

        /*  Get Value */
        $custom_field_value = isset( $_POST['custom_price'] ) ? $_POST['custom_price'] : '';

        /*  Save to _options table (requested answer) */
        $option_name = $post_id.'-custom-price';
        $wpdb->replace(
            'wp_options',
            array(
                'option_name' => $option_name,
                'option_value' => $custom_field_value,
            ),
            array(
                '%s',
                '%s',
            )
        );
    

        /*  Save to postmeta table (normal for woocommerce) */
        $product = wc_get_product( $post_id );
        $product->update_meta_data( 'custom_price', $custom_field_value );
        $product->save();
