B Correct answer
Explanation
Cloud seeding is a type of weather modification. This method was started in 1946. This is done in order to increase the amount of rain in a particular region. This method focusses on to change the amount of precipitation that falls from clouds. The method uses dispersing of certain substances into the air that will serve as cloud condensation or ice nuclei. These materials can alter the processes within the cloud. 
Thus, the correct answer is option B.
