B. 1 and 2 only
Feldspar is the most abundant mineral group, making up about half of the Earth's crust. Thus, statement 1 is correct. Feldspar minerals typically exhibit colours ranging from white and light cream to salmon pink. Thus, statement 2 is correct. Feldspars are primarily aluminosilicates of potassium, sodium, and calcium. Magnesium is not a common element in feldspar. Thus, statement 3 is incorrect. Therefore, only statements 1 and 2 are correct. Answer: 1 and 2 only
