A customer is recruited $($e$.$g$.,$ via email$)$ to go to a website, where they are given a budget and have an opportunity to buy the new product, which is offered among competitors' or related products. Virtual grocery store aisles are displayed $($sometimes in $3-$D or virtual reality, but often just in a $2-$D view$)$ that provide the same information the customer would see on a typical trip to the grocery. There would be row after row of pictures of competitors' products, and the new product embedded, on the "shelf," as it would be when eventually launched. The marketer is looking for how often the new product is selected in this quasi$-$realistic context. What is this an example of$?$

a$.$ An area test market

b$.$ A simulated test market

c$.$ An electronic test market

d$.$ A focus group
