{'talc': [0, 0, 1, 0], 'zinc': [1, 0, 0, 2], 'calcium': [2, 0, 0, 4], 'magnesium': [1, 0, 2, 3], 'tin': [0, 0, 0, 1], 'oxygen': [3, 0, 1, 0], 'silicon': [0, 0, 1, 0], 'sulphur': [0, 0, 0, 2]}
The correct answer is option 3: Magnesium, silicon, and oxygen. Talc is a type of mineral that belongs to the silicate family. It is composed of three main elements: magnesium (Mg), silicon (Si), and oxygen (O).
Option 1, Zinc, calcium, and oxygen, is incorrect. While talc may contain small traces of zinc and calcium, these elements do not make up its primary composition.
Option 2, calcium, oxygen, and tin, is also incorrect. Tin is not a component of talc and is not commonly found in this mineral.
Option 4, zinc, tin, and sulfur, is incorrect. Talc does not contain sulfur or tin, so this option is incorrect.
Therefore, option 3, magnesium, silicon, and oxygen, is the correct answer as these elements make up the composition of talc.
