[单选题]Which following statement about reporting V1 and Vr is correct?
A.When the IAS reaches V1, if V1 and Vr are different, PNF report “V1”; if they are the same, PNF report “rotate”.
B.When the IAS reaches V1,if V1 and Vr are different, PNF report “V1” ; if they are the same, PNF report “V1” or “rotate”.
C.IF V1 and Vr are different, PNF report V1 when the IAS reaches “V1”; if they are the same, PNF report “V1” and “rotate”.
D.AS IAS reaches V1, PNF report V1 and rotate immediately due to “V1” is close to Vr.
