(A) Chadwick’s sign is a presumptive sign of pregnancy. The coloration may not subside from past pregnancy or could be caused by other situations that create vasocongestion.

(D) Breast tenderness and enlargement is a presumptive sign because it may be due to other conditions, such as premenstrual changes.
