Discovery sampling is one of the major activity that will uncover signs of fraud or will help confirm or ally suspicion: a) TRUE b) FALSE

Yes. True. The circumstances can be identified by observation after the sampling identification and more in the nature of a personal skill...that is what I feel, personally.

Yes. With discovery sampling, discovery of atleast one error will cause the entire population to be rejected or where the sample is error-free will cause the population to be accepted entirely.

Absolutely correct.

a. True.....will definitely alert about a potential fraud but could not fully rely on this method to detect frauds.
