According to the test bank, the answer is D. Is this an error? Shouldn't it be A?

An administrator receives reports from users in an office that their 802.11g wireless connectivity has been problematic since the installation of the new wireless phone system. At which of the following frequencies are both systems operating at to cause this issue?
A. 2.4 GHz
B. 900 MHz
c. 1.1 GHz
D. 5 Ghz

    Yup its A
    802.11a 5Ghtz
    802.11b 2.4Ghz
    802.11g 2.4Ghz

    802.11n 5Ghtz\2.4Ghz

    And rearding the phone frequencies (per Wiki atleast)
    In the United States, seven frequency bands have been allocated by the FCC for uses that include cordless phones. These are:
    • 1.7 MHz (1.64 MHz to 1.78 MHz & up to 5 Channels, AM System)
    • 43–50 MHz (Base: 43.72-46.97 MHz, Handset: 48.76-49.99 MHz, allocated in 1986 for 10 channels, and later 25 Channels, FM System)
    • 900 MHz (902–928 MHz) (allocated in 1994)
    • 1.9 GHz (1880–1900 MHz) (used for DECT communications outside the U.S.)
    • 1.9 GHz (1920-1930 MHz) (developed in 1993 and allocated U.S. in October 2005, esp. re DECT 6.0)
    • 2.4 GHz (allocated in 199icon_cool.gif
    • 5.8 GHz (allocated in 2003 due to crowding on the 2.4 GHz band).

    So yeah long story short the testbank answer is just wrong
