Given below are two statements one is labelled as Assertion A and the other is labelled as Reason R : Assertion A : The amphoteric nature of water is explained by using Lewis acid/base concept. Reason R : Water acts as an acid with NH3NH_3NH3​ and as a base with H2SH_2SH2​S. In the light of the above statements choose the correct answer from the options given below :
  1. A
    Both A and R are true and R is the correct explanation of A.
  2. B
    Both A and R are true but R is NOT the correct explanation of A.
