Answer:
b. Opt-out model
Step-by-step explanation:
The opt-out model permits the collection of personal information until the consumer or customer specifically requests that the data should not be collected. The opt-out model majorly uses the written-form of agreement. In other words, the consumer has to expressly put it in written form that his information or other data should no longer be collected. Until the consumer clearly decline consent, consent is given in an opt-out model.
Another model of informed consent is the opt-in model in which a producer, an analyst, or a business is prohibited from collecting any personal information except the owner of the information allows it. It could also be in written form.
