Answer: D

Correct answer: All of the above are contained in the OBDC Level 2 API

The conformance levels are cumulative: a Level 2 driver supports everything in the core API and everything in Level 1 as well as its own additions. So committing and rolling back transactions, connecting to data sources, and connecting with driver-specific information are all available at Level 2, having been introduced at the levels below.
