Space rockets that are used to launch satellites into orbit protect their engine components from violent turbulence and G forces by encasing them in hard metals. The most common metal used for this purpose is Titanium; yet, even with its tensile strength of nearly 100,000 psi, engine components can still be damaged during missions. Tungsten Carbide, a synthetic metal, is four times harder than Titanium and considerably more resistant to G forces and heat. Therefore, to better protect rocket engines, engineers should use Tungsten Carbide for engine encasing instead of Titanium.

Which of the following, if true, best supports the conclusion of the above argument?

A. Tungsten Carbide can also be used to add ballistic protection to astronaut space suits.
B. The increased weight associated with the shift to Tungsten Carbide encasing would create stability and maneuverability problems for most rockets.
C. Tungsten Carbide is a material commonly used for robots involved in commercial manufacturing.
D. Most scientists believe that Tungsten Carbide is just as scratch-resistant as Titanium.
E. Tungsten Carbide offers better protection from turbulence and high velocity impacts and has a tensile strength well over 100,000 psi.
