Answer - A - OFDM uses 48 312.5 KHz subcarriers for transmitting data.

Key Takeaway: OFDM is a broadband multicarrier modulation method that offers superior performance and benefits over older, more traditional single-carrier modulation methods. OFDM uses 52 subcarriers, but only 48 of them are used to transport data. The other 4 subcarriers are used as pilot carriers.
