Quizplus · Accepted Answer

Once hemoglobin has joined with oxygen, it becomes oxyhemoglobin, which is bright red in color.

Choice C is incorrect because reduced hemoglobin refers to hemoglobin that has released oxygen, becoming darker in color. Choice D is simply the generic term for hemoglobin and doesn't describe its state once it has joined with oxygen.
