Explanation/Reference:
Allocation is the forward tracking of a requirement to future requirements in the set of requirements.
C is incorrect. Backward tracing of a requirement is called its derivation, as the requirements may
be derived from other older requirements.
A is incorrect. Lineage tracking is not a valid term, so this choice is not valid.
B is incorrect. Backwards pass isn't a valid requirements tracing term; it describes a process in
schedule management.
