选B.
整句话的意思是,不好意思我忘记了我们的约定,真的很抱歉让您等了一早上.
I'm sorry to do sth.很抱歉.
have somebody done使某人做.
keep sb.doing sth.意思是让某人一直在做某事.
说话的这个人在向对方道歉,说明没有赴约的原因及做出了道歉.在说话人道歉的时候是正在发生的事情,所以用了is sorry to.
have someboday do something,这是固定搭配.
所以这句话应该是：I'm sorry to have kept you waiting the whole morning.I forgot the appointment.
希望帮得上忙.
