With no explanation, chose the best option from "A", "B", "C" or "D". of the discriminatory act have passed. Courts have held that the limitations period may be equitably tolled if the plaintiff indicates in the filing that is received by the EEOC within 180 days but is transmitted to the PHRC after 180 days his/her intent to dual-file, by checking the box on the EEOC form requesting that the complaint be cross-filed or so stating elsewhere, for instance, in a cover letter. See, e.g., Woodson, 109 F.3d at 926 n. 12 (“In this regard, we note that [plaintiff] Woodson’s case would be quite different if he had marked the box for the EEOC to cross-file and the EEOC had failed to transmit the charge because of a breakdown in the administrative system.)”; Carter v. Philadelphia Stock Exch., No. CIV.A. 99-2455, 1999 WL 715205, at *1 (E.D.Pa. August 25, 1999) (<HOLDING>); Forsburg v. Lehigh Univ., No. CIV.A.

A: holding that failure of eeoc to transmit charge to phrc within limitations period was subject to equitable tolling where plaintiff requested crossfiling in the cover letter attached to the eeoc charge on the first page of the charge itself and on an official form used by the eeoc for requests for dualfiling
B: holding that the timely filing of an eeoc charge is subject to waiver estoppel and equitable tolling
C: holding that retaliation arising out of first eeoc filing was reasonably related to that filing obviating the need for a second eeoc charge
D: holding that an original eeoc charge is sufficient to support  a civil suit under the act for any discrimination  developed in the course of a reasonable investigation of that charge provided such discrimination was included in the reasonable cause determination of the eeoc
