While on vacation, you notice a product that you’ve never seen before in the grocery store. after doing some research, you find that the product is only temporarily available in the geographic location where you were. which step of the new product development process is this product most likely in?

The answer is: Commercialisation.

Explanation:

There are different steps while product development, the basic ones in this order are:

The first six steps, do not involve "the market" itsef, as in order to be able to find a product on the market, it has had to go through all the other steps; firstly, because you cannot launch a product without having made a prototype of it first, or launching a product without knowing how much it will cost, it is not normal... You can't also find a product on the market before having planned it or reserched about it... So the fact of finding a product "temporarily" on the market in an specific geographic area, means that the commercialisation has just started.
