Which tells when things are due and the timeframe for working on the project? the chosen goals
the schedule
the research method
the requirements

Lets work through them first:

The goals tell you what you want to accomplish overall, not when you need it done so it doesn't work

the research method tells you how you need to do a project

The requirements are similar to the goals. The only difference is the requirement are the bottom line, meaning you HAVE to have these to finish.

The schedule tells you when things will happen or end so it would be your answer

B. Schedule
