Which is a symptom that is typical in people who have cancer? resistance to insulin sores that do not heal onset of a gluten allergy sensitivity to alcohol

The correct answer is option B,  sores that do not heal

Reason -

If someone is having a non-healing sore then they must consult the doctor , as there are high probabilities that this person might be having cancer. Generally the sores heal quickly and in case if there persists a sore which is not healing since a long time along with persistent red or white patches in and around the sore, it is advisable to consult a doctor. In some cases, these sores may have arisen due to poor air circulation  but it would be advisable to consult a doctor anyhow.

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.
