Millie was nutritionally deprived during early childhood, resulting in skeletal growth stunting. after she was adopted she ate a diet rich in vitamins and minerals and engaged in regular, age-appropriate exercise. as an adult she may be at increased risk for

The right answer is a difficult labor when she gives birth.

Millie does not have a risk of obesity since she practices regular physical activity,

Millie has no risk of becoming anorexic since she adapts a diet rich in vitamin and minerals.

Millie has suffered a bone growth delay due to malnutrition in her childhood, this may affect her labor of delivery when she is pregnant, since the bones at the uterus are not wide enough and clear, which reduces the size of the pelvis and cervix, and makes difficult the exit of the baby.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
