C. Poison gas attacks were often large-scale and unpredictable.

Explanation:

These were two of the reasons why chemical warfare was considered to be a particularly deadly threat during World War I. First of all, chemical warfare was a serious threat due to the fact that soldiers could not analyze the compositions of the chemicals employed. This meant that soldiers were unable to adequately prepare for each type of threat. Moreover, poison gas attacks could not be accurately directed to specific people. Instead, they harmed everything in sight. This meant that poison gas attacks were often large-scale and unpredictable.
