Choice "C" is correct.  An endorsement that includes the words "without recourse" is called a "qualified" endorsement.  When an endorser signs without recourse, the endorser does not undertake the contract liability of an endorser. Choice "a" is incorrect. A blank endorsement is one that does not name a person to be paid.  Such an endorsement makes the check bearer paper, which can be transferred simply by delivery. Choice "b" is incorrect. A special endorsement is a check that names a new payee.  It makes the check order paper.  Further transfer requires the signature of the named payee and delivery to the new transferee-holder.Choice "d" is incorrect. A restrictive endorsement is one that purports to limit further transfers of the check.  Such endorsements generally are not effective except to the extent that they limit the transfer to the collection system (e.g., for deposit only).
