The "end-point list List" specifies a list of multicast responders on the source device.
We need to create the list first, before assigning it to the UDP jitter operations.

The good response is C.
Here is the Lab cisco to configure ip sla to perform a UDP jitter
R1# udp-jitter 172.16.22.254 65051 num-packets 20
R1# request-data-size 160
R1# frequency 30
R1# exit
Only B specifies a destination as a multicast address, and we're asked about MULTICAST jitter. You need the remaining parameters in the udp-jitter because of the multicast address.
I think there is only the '-' missing... needs to be 'B' because endpoint-list is mandatory:
udp-jitter {destination-ip-address| destination-hostname} destination-port endpoint-list endpoint-list [ssm] [source-ip ip-address] [source-port port-number]
[num-packets number-of-packets] [interval interpacket-interval]
The question states that this is about multicast jitter so B is correct.
When configuring IP SLA, the available commands CHANGE when you specify a multicast address. For example "udp-jitter 239.1.1.1 ..." allows you to enter an endpoint list. This "endpoint" option doesn't appear as valid syntax when using regular class A/B/C addresses.
yes, that is true:
cisco_R3(config-ip-sla)#udp-jitter 239.1.1.1 65000 endpoint-list ?
WORD Endpoint list name <<<<<<<<<<<<<<<<<<<<< IP multicast range
cisco_R3(config-ip-sla)#udp-jitter 10.0.0.22 ?
<1-65535> Port Number. Recommended ports greater than 1023. For codec
options recommended port range is an Even Port range between
16384-32767 or 49152-65535
cisco_R3(config-ip-sla)#udp-jitter 10.0.0.22 65000 ? <<<<<<<<<<<<< "normal" IP addr
codec codec type to be configured
control Enable or disable control packets
interval Inter Packet Interval
num-packets Number of Packets to be transmitted
source-ip Source address
source-port Source Port
<cr>
cisco_R3(config-ip-sla)#udp-jitter 10.0.0.22 65000
Basically you could argue that A, B and D are correct answers but only with regards to UDP Jitter IP SLA configuration. This question refers to multicast network meaning only B is correct as it identifes a multicast responder in the command line
B is correct
