Best answer
Correct option is (c) Gunite

The best I can explain: A cement gun is used to deposit the Gunite mixture on the concrete surface under pressure of about 20 N/cm^2 to 30 N/cm^2. The cement is mixed with slightly moist sand and the necessary water is added as the mixture comes out from the cement gun.
