(A) Except as provided in subparagraph (B), no individual shall be entitled to a monthly benefit under subsection (a), (b), (c), (e), or (f) for any month prior to the month in which he or she files an application for benefits under that subsection if the amount of the monthly benefit to which such individual would otherwise be entitled for any such month would be subject to reduction pursuant to subsection (q).

(B) (i) If the individual applying for retroactive benefits is a widow, surviving divorced wife, or widower and is under a disability (as defined in section 423(d) of this title ), and such individual would, except for subparagraph (A), be entitled to retroactive benefits as a disabled widow or widower or disabled surviving divorced wife for any month before attaining the age of 60, then subparagraph (A) shall not apply with respect to such month or any subsequent month. (ii) Subparagraph (A) does not apply to a benefit under subsection (e) or (f) for the month immediately preceding the month of application, if the insured individual died in that preceding month. (iii) As used in this subparagraph, the term “retroactive benefits” means benefits to which an individual becomes entitled for a month prior to the month in which application for such benefits is filed.
