Result
Your answer: —  Â·  Correct: D
Explanation

The Earth's crust is primarily composed of eight major elements. Oxygen is the most abundant element, constituting approximately 46.1% to 46.6% of the crust by mass. Silicon follows as the second most abundant at roughly 27.7% to 28.2%. Other significant elements include aluminum (8.1%), iron (5.0%), calcium (3.6%), sodium (2.8%), and potassium (2.6%). Among the major elements listed in the options, magnesium is found in the lowest quantity within the crust, accounting for approximately 2.1% to 2.33% of its mass. While magnesium is more prevalent in the Earth's mantle (23%) and the Earth as a whole (12.7%), it is the least abundant of the primary crustal elements mentioned in the provided choices. Therefore, oxygen and magnesium represent the highest and lowest quantities respectively among the given pairs.
