Answer and explanation

Correct answer D

After the international search report and written opinion, a PCT applicant may enter the national phase early on an express request (Article 23(2)). The applicant may send informal comments on the written opinion to the International Bureau, amend the claims under Article 19, and file a demand for international preliminary examination under Chapter II (Article 31), with amendments under Article 34. There is no procedure for a formal reply to the ISA on its own report and opinion; the place to argue is Chapter II.
