The most accurate way to state an "odds ratio" is:
a. the risk of acquiring the disease among the exposed versus the non-exposed
b. the odds of a disease being attributed to a certain exposure.
c. the odds of getting a disease in the exposed versus the odds of getting the disease in the non-exposed

c. The odds of getting a disease in the exposed versus the odds of getting the disease in the non-exposed

Step-by-step explanation:

Odds ratio (OR) is statistic which quantifies strength of association between the two events, say, A and B.

Odds ratio may be defined as ratio of odds of A in presence of B and  odds of A in absence of B, or vice versa.

If the two events are independent, the OR becomes equal to 1.

If OR is greater than 1, then A and B are positively correlated and compared to the absence of B, the presence of B raises the odds of A or vice versa.

If OR is less than 1, it means that A and B are correlated negatively, and presence of the one event reduces odds of other event.

The best state is shown by C. So, C is the answer where A is the event of getting the disease and B is some exposure to something.
