answer is c) 2
circles are intersecting
let c1 and c2 are centres of circle  and  d is distance between c1 and c2 and r1 and r2 are radii of circles
  1. if d> r1 + r2  4 common tangents
  1. d= r1+ r2   3 common tangents
  1. and if    r1 – r2  
when u calculate all thes parameters in ur question then statement 3 is verified so 2 commom tangents
