Rejected Green Card Application

My brother got his Form I-797C Notice of Rejection and Resubmittence. It said that the Form I-130 Petition for Alien Relative was not filled out correctly. He did a concurrent filing of the Form I-485 Application to Register Permanent Residence or Adjust Status, Form I-130 Petition for Alien Relative and Form I-864 Affidavit of Support Under Section 213A of the Act.

All of these forms came back together. Are they all rejected? Should he resubmit the entire application? What should we do?
