Once you suspect a person of double dealing, you ought to keep him at arm’s …… A. distance B. length C. aim D. width

distance
length
aim
width

The correct answer is distance.

The phrase “keep someone at arm’s length” means to avoid getting too close to them, either physically or emotionally. This is often done when someone is suspicious of the other person’s motives or intentions.

The other options are not correct because they do not make sense in the context of the phrase.

  • Length does not make sense because it is not possible to keep someone at a certain length.
  • Aim does not make sense because it is not possible to aim someone at a certain distance.
  • Width does not make sense because it is not possible to keep someone at a certain width.

I hope this helps!
