Answer:The answer is the first one."Stepped up the Deployment etc."
Explanation:The treaty limited each side to only one ABM deployment area (i.e., missile-launching site) and 100 interceptor missiles. These limitations prevented either party from defending more than a small fraction of its entire territory, and thus kept both sides subject to the deterrent effect of the other's strategic forces.
