Final Answer :
D
Explanation :
The positive predictive value precisely represents the probability of having a disease given that the result from a test was positive.Sensitivity and specificity are the abilities of a test to recognize people with and without the disease,respectively.However,they do not provide information regarding the probability of having a disease given the result of the test.Negative predictive value represents the probability of not having a disease when the result of the test is negative.
