B)an unsaturated solution with some undissolved solid
C)a saturated solution with no undissolved solid
D)an unsaturated solution with no undissolved solid
E)a supersaturated solution

Given the solubility of sodium chloride is 36.0 g per 100 g of water, 50.0 grams of water could dissolve up to 18.0 grams of sodium chloride at 25ºC (since 36.0 g in 100 g of water scales down to 18.0 g in 50 g of water). Since only 15.0 grams of sodium chloride is mixed with 50.0 grams of water, all of it will dissolve, resulting in an unsaturated solution with no undissolved solid.
