Answer:
concrete
Explanation:
Researchers think regolith on Mars could serve as a replacement for concrete components. The Mars rovers have used gas chromatography, mass spectrometry, and laser spectrometry to determine the composition of martian soil. Mars regolith is mostly silicon dioxide and ferric oxide, with a fair amount of aluminum oxide, calcium oxide, and sulfur oxide. The composition varies from place to place on the planet’s surface because of variability in asteroid collisions and the weathering by wind and water, in ancient oceans and in some modern water flows. But no spacecraft has returned to Earth with actual samples of the material.

Just us having those privileges and they don't makes me feel bad for them.
Among the choices, option B. Hasn't, is a singular contraction. "Hasn't" is the shortened word for "has not". The rest of the choices are plural contractions: Don't from do not, Haven't from have not, and Weren't from were not.
