Answer:

B. 180

Step-by-step explanation:

One of the vertexes of figure A is at (1,1)

Its corresponding vertex in Figure B is at (-1,-1).

When a figure is rotated 180 degrees counterclockwise around the origin, we have the transformation rule:

$(x,y)\to(-x,-y)$

Thus, we see that Figure A is rotated 180 degrees counterclockwise.
