Correct Answer is D

Explanation

Choice A rationale

A family history of breast cancer, particularly in a close relative like a sister, is a significant risk factor for breast cancer.

Choice B rationale

Exposure to radiation, particularly in the chest area, increases the risk of developing breast cancer.

Choice C rationale

Current use of oral contraceptives can slightly increase the risk of breast cancer, though the risk diminishes after stopping the pills.

Choice D rationale

Age less than 25 years is not a risk factor for breast cancer; risk increases with age.

Correct Answer is D

Explanation

Choice A rationale

Breast tenderness is considered a presumptive sign of pregnancy, as it can result from hormonal changes, but it is not definitive enough to confirm pregnancy.

Choice B rationale

Fetal heart tones detected by ultrasound are a positive sign of pregnancy. However, it is not a probable sign as it is definitive evidence of an existing pregnancy.

Choice C rationale

Fetal movement, often felt later in pregnancy, is a positive sign. It indicates an existing pregnancy but is not used to initially diagnose pregnancy.

Choice D rationale

A positive urine pregnancy test is a probable sign of pregnancy. It detects the presence of hCG (human chorionic gonadotropin), a hormone produced during pregnancy, and is a widely used indicator of probable pregnancy. .
