Query to check USER level Profile Option Value in Oracle Cloud HCM

I needed a query to fetch the profile option values at USER level for Language Preference set by the employee. So here is what I had written, let me know if any change is required.

SELECT
    fnd.language_code
FROM
    fnd_profile_options_b      b,
    fnd_profile_option_values  v,
    per_users                  per,
    fnd_languages_vl           fnd
WHERE
        v.level_value = per.user_guid
    AND b.profile_option_id = v.profile_option_id
    AND per.person_id IS NOT NULL
    AND b.profile_option_name = 'FND_LANGUAGE'
    AND v.level_name = 'USER'
    AND v.profile_option_value = fnd.language_tag
    AND fnd.activation_status = 'ACTIVE'
    AND per.person_id = (select distinct person_id from per_all_people_f where person_number='123456')
