Accepted Answer

UDP is a connectionless protocol, meaning it doesn't establish a dedicated end-to-end connection before data transmission. It also operates on a best effort basis, meaning it doesn't provide any guarantees regarding data delivery, ordering, or duplication. Therefore, options A and C are correct while options B and D are incorrect.
