question help!

I'm preparing IBM 000-M95 test, then I came across some problem, can anyone help me the following question:
Which of the following is TRUE regarding the use of Critical Fields.?
A. Critical Fields are used to identify fields that must agree in order for records to be linked.
B. Critical Fields do not have to match exactly.
C. Only critical fields of a record are used to calculate the composite weights of the record.
D. Critical Fields are fields with missing values.
Answer: A

Pretty sure it's "A". But, that's not the best answer possible..just the best answer out of the ones available.
