If the number of elements in the sets G and A are 3 and 4 respectively, then match the items of List I with those of List II The correct match is A B C D

Options

  1. AV I III II
  2. BV III IV II
  3. CIII IV V II
  4. DI II III IV

Correct answer

A. V I III II

Step-by-step solution

Given that, number of elements in the sets G and A are 3 and 4 respectively. (A) The number of non bijective function from G G to G=3^9=19683 (B) A to A Here, a has 4 choice, b has 3, c has 2 and d has 1 choice. So, number of bijective functions from A to A is =4 3 2 1=24 (C) G to G A So, number of function from G to G A is =12^3=1728 (D) A to A A The number of surjective from G to G A i.e. 4 to 16 is 0 So, A V , B I , C III , D II.
