Long-acting local anaesthetic solution includes bupivacaine, ropivacaine, etidocaine and articaine. If protein-binding of both bupivacine and ropivacaine is compared, then it is 95% and 94%, respectively. Also, clinical during of ropivacaine is 20% less than bupivacaine; therefore 'c' is the most appropriate answer.
