Step 1

Ka is known as the equilibrium constant of an acid which is defined as the ratio of product of 'concentration of all the product' to the product of 'concentration of all the  reactants'.

Step 2

The reaction of Al(NO3)3 with H2O is :

Al(NO3)3(aq) + 3H2O(l) --> Al(OH)3(s) + 3HNO3(aq)

The standard value of Ka for Al(NO3)3 at 25°C is 1.8 x 10-5.

So, The correct option is (B) : 1.8 x 10-5
