1.	On treatment with cold water, an element (A) reacted quietly, liberating a colourless, odourless gas (B) and a solution (C). Lithium reacted with (B) yielding a solid product (D) which effervesced with water to give a strongly basic solution (F). When CO_(2) (E) was bubbled through solution (C), an initial ppt. (G) was formed but this redissolved forming solution (H) when more CO_(2) was passed. Precipitate (G) effervesced when moistened with conc. HCl and gave a deep red coloration to a Bunsen burner flame. (G) on heating with excess of carbon at 2000^(@)C gave (I)QSolution (H) contains a salt. Consider the following statements: (0) It causes permanent hardness of water (i) It can not be obtained in solid state (ili) It causes temporary hardness of water (iv) It can be obtained in solid state Select the correct statements,
