Answer»

Right ANSWER is (b) Cement, LIME

For explanation I would say: In BRICK jack arch flooring, joists are encased in cement mortar, for preventing their rusting from the lime mortar. In this type of flooring, only well-burnt bricks should be used for construction and they are saturated with water before USING them.
