With no explanation, chose the best option from "A", "B", "C" or "D". to PSPs for payphone service is not clearly unrelated to a carrier’s telephone rates and services. As Congress and the Commission have recognized, PSPs must be compensated if customers are to be able to use the dial-around long distance service that the carrier provides. See, e.g., 47 U.S.C. § 276(b)(l)(ordering the Commission to prescribe regulations “[i]n order to promote competition among [PSPs] and promote the widespread deployment of payphone services to the benefit of the general public”). In short, § 201(b) is ambiguous enough that unjust or unreasonable practices can encompass a broad range of activities related to the services provided and rates charged by a long distance carrier. Cf. La. Pub. Serv. Comm’n v. FCC, 476 U.S. 355, 371-72, 106 S.Ct. 1890, 90 L.Ed.2d 369 (1986) (<HOLDING>), superseded by statute on other grounds as

A: holding that the terms charges classifications and practices as used in section 152b of the communications act encompass a companys internal accounting and depreciation practices
B: holding consumer claims under the texas deceptive trade practices act nonassignable
C: holding that statutory damages were appropriate for each discrete violation of that states deceptive trade practices act
