Best answer
The correct answer is (d) zeolites

Best explanation: When aluminium ions replace few ions in a three-dimensional network of silicon dioxide, the overall structure is known as aluminosilicate and it also requires negative charge cations like sodium, potassium or calcium to balance negative charge. Few examples are zeolites and feldspar.
