The objective of using mod_rewrite to achieve SEO URLs is for you to actually change all links on your site to the 'pretty' format, then to make a simple rule that can convert this pretty rule back into the query_string version. In your case you would be using something similar to this...

RewriteEngine On
RewriteBase /
RewriteRule ^([a-zA-Z0-9-]+)/?$ index.php?lang=$1
RewriteRule ^([a-zA-Z0-9-]+)/([a-zA-Z0-9-]+)/?$ index.php?lang=$1&option=$2
RewriteRule ^([a-zA-Z0-9-]+)/([a-zA-Z0-9-]+)/([a-zA-Z0-9-]+)/?$ index.php?lang=$1&option=$2&option_m=$3

This obviously however requires that option will always be included before option_m, if both are truly optional, meaning you can include option_m without option, then there is really no way round it with mod_rewrite alone.
