A．Gary's sister. B．The woman talking with Gary. C．The professor of the course. D．The painter Desiree.
参考答案D解析:Who is Lisa Frank?
细节题。对话中男士问And did you say the painter's name was Desiree?女士回答Yes, but that's just her pseudonym. She only uses that name when she paints. Her real name is Lisa Frank.由此可知Desiree的真实姓名是LisaFrank。因此，正确答案是D。
