Answer:
A. To bend in a different direction.
Explanation:
To deflect something is to change/redirect/reverse its original course & direction.
For example, if you kick a soccer ball and the goal keeper deflects it, they are changing its course so that the ball goes in a different direction rather than going into the goal.
The prefixes, suffixes, and roots in the chart hint at this with:
"Reverse"
"Angle"
"To Bend"
