Group of answer choices

A.incidence of a disease

b. duration of illness

c. point prevalence of a disease

d. 5-years survival rate after surgery

Answer 1

Correct answer is option c - point prevalence of a disease because cross sectional studies both descriptive and analysis study are used.Descriptive simply characterized by prevalence of health outcomes in specific time , it can be point prevalence or period prevalence

Other options are incorrect because in cross sectional studies only snap shot of disease and risk can be studies and not beforeduring after disease emergence

Thus option a which is incidence of disease is also can't be studies in snapshot

Option b and d is also incorrect as it can't be studied under it because in them over time studies need to be done which is not done in cross sectional studies.

Thus correct answer is option C - point prevalence of disease.
