B)802.11a equipment is less expensive than 802.11b.
C)802.11a equipment is backwards compatible with 802.11g equipment.
D)5 GHz UNII bands allows for more non-overlapping channels than the 2.4 GHz ISM band.

The 5 GHz UNII bands allows for more non-overlapping channels than the 2.4 GHz ISM band.
Key Takeaway: The lower portion of the 5 GHz UNII band and the 2.4 GHz ISM band are the same width of about 100 MHz. The UNII bands allow a larger useable portion than the 2.4 GHz ISM band. Hence, it yields a maximum of 4 non-overlapping DSSS channels.
