AI Explanation

The correct answer is B) A leak in the flange gasket while hydrostatically testing the hose. According to U.S. regulations, a small cut in the hose cover that just pierces the reinforcement (A), slight oil seepage between the hose and flange connection (C), or evidence of internal or external deterioration (D) would disqualify a nonmetallic hose as being suitable for use in transferring oil. However, a leak in the flange gasket while hydrostatically testing the hose would not disqualify the hose, as the hose itself is still intact and functional. The hydrostatic test is meant to check the overall integrity of the hose, and a leak in the gasket would not indicate a problem with the hose material or construction.
