Answer:
The correct option is A, C and D
Step-by-step explanation:
Option B is wrong because switching on electrical devices could be dangerous during flood as it could lead to electrocution. It could also destroy the electrical appliances. Also, switching on electrical devices does not prepare one for flood but rather, one should be prepared/ready to evacuate. Flooding some times, starts from another location and moves towards new locations, in cases like this, one should switch to drinking of bottled water until local water (coming from areas that have already been affected by the flood) is declared safe.
Also, furnitures (that are easily destroyed by water) are to be kept/stored in a safe place (temporarily) - away from where the water from the flood will be able to have direct contact with them.
