Nitrogen triiodide

[BTGmoderatorDC]

Nitrogen triiodide is a highly explosive chemical that is easy to make from only two ingredients: ammonia and concentrated iodine. However, no terrorists are known to have ever used nitrogen triiodide in an attack.

Which of the following, if true, is the most likely explanation for the discrepancy described above?

(A) Ammonia can be bought in a grocery store, but concentrated iodine must be obtained from somewhat more restricted sources, such as chemical supply houses.
(B) Nitrogen triiodide is only one of several powerful explosives that can be made from ammonia.
(C) Many terrorists have been more focused on acquiring weapons of mass destruction, such as nuclear or biological weapons, than on developing conventional chemical explosives.
(D) Airport security devices are typically calibrated to detect nitrogen compounds, such as ammonia and ammonium compounds.
(E) Nitrogen triiodide is extremely shock sensitive and can detonate as a result of even slight movement.

What is the best option and why is it the best option?
