According to the World Times Academy - a project of Jahangir Publishers- Islamic Studies paper can be opted in Urdu as well as in English. A month or so ago, I contacted FPSC inside source and he also made the same response. It is also worth-noting that valuable sources shared the news through FPSC sources that FPSC has restored the medium of Urdu and English both for the said paper.
