Explanation

Option A is correct because the Pensky-Martens apparatus measures flash points above 50°C. Option B is true since paraffinic crude oils have characterization factors over 12. Option C is accurate as the Abel apparatus is used for flash points under 50°C. However, option D is false because a high viscosity index indicates that the oil's viscosity changes little with temperature, not a high susceptibility.
