Answer:
A. premarket testing.
Step-by-step explanation:
The pre market testing is when people from a certain business send products to people that are the target of that product to see if they would use it, continue to use it and how much would they be willing to pay for that product, this is done prior to the launch of the product, in order to get to know better the consumer and how they can improve their product, also to see if it is viable to start mass production and launch it into the market, so what Lorraine is doing is premarket testing.
