Answer:
(1) increasing funding to its existing R&D department to expand to the development of AI (artificial intelligence) technology, needed for self-driving vehicles
This strategy would produce the benefit of puttinig the company on the edge of the development of AI in order to produce driverless vehicles.
The risk is that the investment could be too high for the initial benefit, since there is no certainty that driveless cars will be in the market in the short-term.
(2) launching a fully owned subsidiary (a new company that it owns and controls) focused exclusively on AI
This strategy would produce a similar benefit as the strategy above. However, it could also benefit from a little bit less administrative control because in this case, the AI development would be in charge of a subsidiary, not a division.
The risk is the same as above: initial investments may be too high for the initial benefits.
(3) partnering with a major Silicon Valley tech company that has already made considerable progress on AI technology.
This strategy produces the benefit of requiring less investment while still putting the company on the edge of AI research. However, the risk lies in loss of control over the thecnology, and possible future conflicts with the partner company.
