About TDD and FDD contrast description, which is correct?

• A.For 20MHz bandwidth cell, the FDD uplink and downlink each occupy 20MHz, and the TDD uplink and downlink share 20MHz.
• B.The subframe ratio of LTE TDD makes the delay of some information feedback (such as HARQ ACK/NACK, or CQI) less than the delay of LTE FDD. Therefore, the RTT (Round-trip Time) of LTE TDD is slightly smaller than LTE FDD.
• C.LTE TDD is a time division system. When the terminal is allocated the same number of RB, the LTE TDD throughput rate is lower than the LTE FDD.
• D.Since the LTE TDD in GP present in such LTE TDD spectral efficiency slightly lower than LTE FDD.
