Which of the following statements concerning contaminating materials on a surface of a
penetrant test specimen is false
A. The contaminant may be of Composition that attacks the penitent, and reduces the
fluorescent or color of penetrate
B. Contaminant reduce or even prevent capillary action by the penetrant
