Which wireless standard has bandwidth up to 54 Mbps and signals in a regulated frequency spectrum around 5 GHz?

The correct answer is A. 802.11a. IEEE 802.11a operates in the 5 GHz frequency band and supports a maximum bandwidth of 54 Mbps. 802.11b operates at 2.4 GHz with up to 11 Mbps. 802.11g also achieves 54 Mbps but operates at 2.4 GHz, not 5 GHz. 802.11i is a security amendment (WPA2) and not a data-rate or frequency
