A C should be replaced with B12 whereas E should be replaced with A.
B Positions of lemon and peanut butter should be interchanged whereas sodium and potassium should be replaced by calcium and phosphorus respectively.
C Positions of calcium and sodium should be interchanged whereas E should be replaced with D.
D Sodium and potassium are correctly mentioned hence should not be replaced but calcium should be replaced with iron.
