The correct answer is option 1, Pakistan.

In November 2013, Pakistan successfully test fired the Hatf DC (Nasr) short range surface to surface multitube ballistic missile. This missile is developed by Pakistan and is capable of carrying both nuclear and conventional warheads.

Option 2, China, is incorrect as China is not known to have test fired the Hatf DC (Nasr) missile. China has its own missile technology and missile development programs.

Option 3, Iraq, is incorrect as Iraq does not have the capability to develop or test fire ballistic missiles like the Hatf DC (Nasr).

Option 4, Iran, is also incorrect as Iran has its own missile development program and has developed its own ballistic missiles, but it has not test fired the Hatf DC (Nasr) missile, which is developed by Pakistan.

Therefore, the correct answer is option 1, Pakistan.
