Remove all data related to plugin as cleanly as possible

Hi Karan,
Thank you for using our plugin,

If you want to clear all existing B2BKing data from users, posts, products, settings, custom B2BKing posts, etc., you can run the following snippet once:

// clear options
	global $wpdb;
	$plugin_options = $wpdb->get_results( "SELECT option_name FROM $wpdb->options WHERE option_name LIKE '%b2bking%'" );
	foreach( $plugin_options as $option ) {
	    delete_option( $option->option_name );
	}

	// clear all custom posts
	$post_types = array('b2bking_custom_role', 'b2bking_custom_field', 'b2bking_group', 'b2bking_rule', 'b2bking_offer', 'b2bking_conversation');
	foreach ($post_types as $type){
		$allposts= get_posts( array('post_type'=> $type,'numberposts'=>-1) );
		foreach ($allposts as $eachpost) {
			wp_delete_post( $eachpost->ID, true );
		}
	}

	// clear user metadata
	$wpdb->query("DELETE FROM $wpdb->usermeta WHERE meta_key LIKE '%b2bking%'");

	// clear product metadata
	$wpdb->query("DELETE FROM $wpdb->postmeta WHERE meta_key LIKE '%b2bking%'");
