Mel is a salesperson for a technology services company. He wants to expand collaborative involvement between his company and his buyer's company. Which of the following activities is most likely to help Mel achieve his goal?

I couldn't find any possible options, but if Mel wants to expand collaborative involvement between companies, he should try to make them work together.

Mel is probably trying to sell a new software or technological device to his client, and in order to try to convince the client that his offer is the best, he could suggest that the engineers from his company work together with the engineers of the buying company in order to solve any issues or doubts that may exist. This doesn't necessarily mean that they have to come together and work side by side, now you can work together using Skype of other communications app.
