Before going ahead I want to discuss abou the biological weapon. what Is biological weapons ? Biological weapons are those which are prepared by using the surrounding or natural things such as banana tree , woods , etc to get out rid of any oroblem ,such weapons are called as biological weapons . Now the answer of the question becomes more clear that the disaster managment committee use such weapons to help the affected people because if the place is prone of disaster there will no any outsr source reach qickly. So the functions of biological weapon is important.
Sorry Hrithik I am unsatisfied with your answer as you actually misunderstood the question!! question is actually what are functions of dm committee to rescue the people affected by biological weapons like those were used in Hiroshima nakasaki and I don't mean that dm committee uses biological weapons...that's wrong!!!
