Question is asking how many non-overlapping 5GHz channels there are if UNII-2c isn't available. Correct answer should be six non-overlapping channels, not four. Refer to the following chart: https://www.mbreviews.com/wp-content/upl...scaled.jpg

For 40MHz channels, there are two in UNII-1, a further two in UNII-2a and another two in UNII-3.
