Collection of exchangeable binary outcomes for the same covariate data are called . . . . . . . . outcomes.

Option B, direct outcomes, are outcomes that are directly caused by the treatment. For example, if a patient is given a new drug, the direct outcome would be whether or not the patient recovers from their illness.

Option C, binomial outcomes, are outcomes that can only have two possible values, such as success or failure. For example, if a coin is flipped, the binomial outcome would be whether or not the coin lands on heads.

Option D, none of the mentioned, is not the correct answer.
