The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of the elemental composition of the Earth's crust.
Step 2: Detailed Explanation:
The most abundant element in the Earth's crust is oxygen (A).
Oxygen makes up about 46.6% of the Earth's crust by weight.
Silicon is the second most abundant element (27.7%).
Aluminium (8.1%) and Iron (5.0%) are also abundant.
Thus, oxygen is the most abundant element.
Step 3: Final Answer:
Thus, the most abundant element in the earth's crust is oxygen, which corresponds to option (A).
