Leak at the bath sink drain? inspect for tightness, check for washer placement or look for any cracks. Most of these assemblies are made of ABS or plastic and the plastic washers are tapered to seal as they get tighter NOTE: be careful not to over tighten or this can result in a fine hairline crack and difficult to diagnose. Also do not use any plumbers putty on cultured or marble basins because over time the chemicals will eat away the sink drain hole and cause more problems for you, use 100% silicone here instead and be generous, as you tighten the excess will fill any voids and cover well. Clean excess up with a clean damp rag and no other chemicals IE paint thinner, spirits etc.
