Hello!

The subject of this sentence is "Yo" (I), so we must use the first-person singular conjugation.
Thus, the correct conjugation ends with an "o", or "Pruebo". Choice A is the correct answer.
Answer:
The answer is: Commercialisation.
Explanation:
There are different steps while product development, the basic ones in this order are:
- Idea generation
- Research of your product
- Planning
- Prototyping
- Sourcing
- Costing
- Commercialising
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.
