A metal reacts with water to form an alkaline solution. If the aqueous solution of the chloride of this metal is known as brine, to which period and group does this metal belong in the Modern Periodic Table?

Given below are two statements: Statement I: The halogen that forms the longest bond with hydrogen in HX has the smallest covalent radius in its group. Statement II: A group 15 element's hydride (EH3) has the lowest boiling point among the corresponding hydrides of group 15 elements. The maximum covalency of that element E is 4. In the light of the above statements, choose the correct answer.

Match List-I (Reagents) with List-II (Name of Reaction) and select the correct option: List-I: A. NH2-NH2, KOH B. [Ag(NH3)2]OH C. Aq. CuSO4 + Sodium Potassium Tartrate + KOH D. Zn-Hg, HCl List-II: I. Tollen's Test II. Clemmensen Reduction III. Wolff-Kishner Reduction IV. Fehling's Test
