Final answer:
The oozing ulcers on the patient's knee are described as having the same color and consistency as 'blancmange' milk pudding, which means they are white and have a pudding-like texture.
Step-by-step explanation:
When comparing the characteristics of the oozing ulcers on the patient's knee to blancmange, a type of milk pudding, we can determine that the ulcers resemble this dessert in color and consistency. Therefore, the correct answer is A) It is as white as milk pudding. This comparison indicates that the ulcers have a creamy, white appearance similar to that of the referred dessert. This descriptive phrasing does not imply that the ulcers are greenish yellow, red, or brown, which are other possible colors that could indicate different types of infection or substances like blood in the wound.
