A particle P starts from the point `z_(0)=1+2i`, where `i=sqrt(-1)`. It moves first horizontally away from origin by 5 units and then vertically away from origin by 3 units in the direction of the vector `hati+hatj` and then it moves through an angle `pi/2` in anticlockwise direction on a circle with center at origin, to reach a point `z_(2)`. The point `z_(2)` is given by

A

`6+7i`

B

`-7+6i`

C

`7+6i`

D

`-6+7i`
