The diagram shown above represents the solubility curves of two salts, X and Y, in water, use this diagram to answer the question. If 80 g each of X and Y are taken up in 100 g of water at 353 K we shall have

• A.only 10g of X undissolved
• B.only 16 g of Y undissolved
• C.10 g of X and 16 g of Y undissolved
• D.all X and Y dissolved
• E.all X and Y undissolved
