Let A={2,3,5,7,9}A = \{2, 3, 5, 7, 9\}. Let RR be the relation on AA defined by x R yx\,R\,y if and only if 2x≤3y2x \le 3y. Let ℓ\ell be the number of elements in RR, and mm be the minimum number of elements required to be added in RR to make it a symmetric relation. Then ℓ+m\ell + m is equal to:
  1. (1)23
  2. (2)25
  3. (3)21
  4. (4)27
