Answer: Possibly all of them.
The information given is not enough to decide what gets affected. Normally, during phase A, you will define the scope of the ADM cycle which will dictate what should be done in each phase (or if the phase is not required). Also in phase B, you will get enough information from the baseline architecture and requirements that will drive the Information and Technology architecture in the next 2 phases. Also, usually, you will iterate between B - D enough times as necessary until you have exhausted all possible solutions.
One doesn't just decide which phases to activate/skip at the onset of the ADM cycle.
The question was just for my understanding about the phase, for my studies.
I thought of a scenario, where we have an existing EA for a transportation company and if they buy some new vehicles, which is say by factor 5 of their existing number of vehicles, how would they actually manage the change.

This is why TOGAF 9 uses generic language. Phase C is called Information Systems architecture, not IT architecture. Phase D is called Infrastructure architecture, not Hardware architecture. Your "Information System" can all be on Post-Its, that's fine.. you can still use TOGAF principles to manage your Post - Its. Your "Infrastructure" could be a shoe box where you store your post-its. THat's fine. You can still use TOGAF principles. It doesn't have to be all IT.
For example, TOGAF defines "enterprise" as
any collection of organizations that has a common set of goals. For example, an enterprise could be a government agency, a whole corporation, a division of a corporation, a single department, or a chain of geographically distant organizations linked together by common ownership.
Enterprise is collections of organizations. That means everything in the organization
It defines architecture as
"The fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution."
Again this can be anything, not just IT systems.
And enterprise architecture is simply architecture of an enterprise, or IOW, the fundamental organization of organizations thhat have a common set of goals, their relationships to each other and the environment, and the principles governing their design and evolution
That encompasses everything, not just IT.
