Bond (007) wants to move from a point A to point D, but here 2 watchtowers (B & C ) are present in the way of A to D. soldier on watchtowers has rifles with range of 1 kilometer. A,B,C,D are in straight line and distance between All points is 1 kilometer respectively. Find the minimum distance covered by 007 in journey between point A to D while his distance from watchtowers is always >=1 .	Choices:  A) 2.14  B) 3.4  C) 1.4  D) 6.21  E) 4.14
bond has to travel on quarter circumference of circle centered B then wakl streight 1 km then again walk on circumference of circle centered C.   = 2*pi*1/4 + 2*pi*1/4 + 1   = 1.57 +1.57 + 1=
