Which statement about an infrastructure basic service set is true according to IEEE 802.11
specifications?
A.
The set also is called an ad hoc network.
B.
The BSSID is generated from the first wireless client that starts up in the IBSS.
C.
The set enables the use of ESS.
D.
No signals are relayed from one client to another client.
The set-up formed by the access point and the stations located within its coverage area are called the basic service set (or infrastructure basic service set, or BSS for short). Each BSS forms one cell.
We can link several BSS’s together (it means we link access points) using a connection called a distribution system in order to form an extended service set or ESS. The distribution system can also be a wired network, a cable between two access points or even a wireless network.
Note: When a station moves from one access point to another in an ESS, it is called roaming

Wireless mobile ad hoc networks are self-configuring, dynamic networks in which nodes are free to move. Wireless networks lack the complexities of infrastructure setup and administration, enabling devices to create and join networks “on the fly” – anywhere, anytime.

Really bad guys !
(from certguide)
The 802.11 standard allows two or more wireless clients to communicate directly with each other, with no other means of network connectivity. This is known as an ad hoc wireless network, or an independent basic service set (IBSS)
It’s a Ad-hoc network !

My apology, it seems to be correct, it was about IBSS (independant Basic Service Set).
Indeed, for Infrastructure Basic Set: (from Wikipedia)
An ‘extended service set’ (ESS) is a set of one or more infrastructure basic service sets on a common logical network segment (i.e. same IP subnet and VLAN).[7] Key to the concept is that the participating basic service sets appear as a single network to the logical link control layer.[7][8] Thus, from the perspective of the logical link control layer, stations within an ESS may communicate with one another, and mobile stations may move transparently from one participating BSS to another (within the same ESS).[8] Extended service sets make possible distribution services such as centralized authentication and seamless roaming between infrastructure-BSSs. From the perspective of the link layer, all stations within an ESS are all on the same link, and transfer from one BSS to another is transparent to logical link control.[9]
