Azotobacter is a non symbiotic bio-fertlizer.They are aerobic, free-living soilmicrobeswhich play an important role in thenitrogen cyclein nature, binding atmosphericnitrogen, which is inaccessible to plants, and releasing it in the form ofammoniumions into the soil.

Rest of the options are symbiotic.
