Starting in the 1960s, the two superpowers signed three significant agreements within a decade. Which of the following treaties was not signed during the 1960s and 70s?

A-Limited Test Ban Treaty
B- Strategic Arms Reduction Treaty I (START-I)
C- Strategic Arms Reduction Treaty II (START-II)
D- Nuclear Non-Proliferation Treaty
E- Anti-Ballistic Missile Treaty

B and C

The correct answer is Option 2 - B and C

Given options:

A-Limited Test Ban Treaty - 1963
B- Strategic Arms Reduction Treaty I (START-I) - 1991
C- Strategic Arms Reduction Treaty II (START-II) - 1993
D- Nuclear Non-Proliferation Treaty - 1968
E- Anti-Ballistic Missile Treaty - 1972

In time, therefore, the US and USSR decided to collaborate in limiting or eliminating certain kinds of nuclear and non-nuclear weapons. A stable balance of weapons, they decided, could be maintained through ‘arms control’. Starting in the 1960s, the two sides signed three significant agreements within a decade. These were the Limited Test Ban Treaty (1963) , Nuclear Non-Proliferation Treaty (1968) and the Anti-Ballistic Missile Treaty (1972). Thereafter, the superpowers held several rounds of arms limitation talks and signed several more treaties to limit their arms.

STRATEGIC ARMS REDUCTION TREATY I (START-I) was signed in 1991.

STRATEGIC ARMS REDUCTION TREATY II (START-II) was signed in 1993.
