  3. Tantalum
  4. Titanium


Answer and Explanation :-

Answer: Option 4

Explanation:

The Moon is similar to the Earth in that it has a crust, mantle, and core. Scientists have samples of the lunar crust and take measurements of properties of the Moon's surface. The crust consists of 43% oxygen, 20% silicon, 19% magnesium, 10% iron, 3% calcium, 3% aluminum, and trace amounts of other elements including 0.42% chromium, 0.18% titanium, 0.12% manganese, and smaller amounts of uranium, thorium, potassium, hydrogen and other elements. These elements form a concrete-like coating called regolith. Two types of Moon rocks have been collected from the regolith: mafic plutonic and maria basalt. Both are types of igneous rocks, which formed from cooling lava.
