None Of the Above
A
Correct answer
Explanation
The exact cause of birthmarks is not fully understood by medical science. While some types of birthmarks may have genetic components or vascular origins, the mother's diet or emotional state during pregnancy is not scientifically proven to cause birthmarks. Option A is correct because it accurately reflects the current state of medical knowledge.
B
Correct answer
Explanation
While dry skin does occur during pregnancy due to hormonal changes and fluid shifts, the most common skin condition is actually hyperpigmentation, particularly melasma (the 'mask of pregnancy'). Other very common pregnancy-related skin issues include stretch marks (striae gravidarum), acne due to hormonal fluctuations, and various pregnancy-specific dermatoses.

Develop problems related with the cardiovascular system
B
Correct answer

High birth weight (macrosomia) is associated with increased risk of developing type 2 diabetes later in life due to metabolic programming and potential insulin resistance. Migraines, high blood pressure in early adulthood, and cardiovascular problems are less directly linked to birth weight in the same way.
