PF: When boxes for the Ethics and Security part (p.15-16 of 20) are ticked in the MSCA PF proposal template the applicant is asked to provide relevant pages in the technical annex. Shall the applicant provide the pages of Part B where ethics and security are explained?

Yes, the page numbers should refer to Part B.

The box accepts also text not just numbers. Therefore, in case of ambiguity, the applicant can insert Part B1 + page number or Part B2 + page number.
