RTC stands for which of the following?

• A. Regional Transit Card
• B. Regional Card with Chip
• C. Regional Discount Cards with a chip
• D. Rail Transit Card

Answer: (C)

The main idea is recognizing what RTC stands for in this context: a regional program that uses a smart card to grant discounts. The best fit is Regional Discount Cards with a chip because it explicitly includes the regional scope, the discount aspect, and the embedded chip feature all together. The other options drop or change one of these elements—regional transit cards omit the discount part, a regional card with a chip lacks the explicit discount focus, and a rail transit card shifts to a rail-specific term and doesn’t emphasize discounts. So the full phrasing Regional Discount Cards with a chip matches the intended meaning and usage of RTC.
