The best answer is a. avoid sparks or open flames. This is because hydrogen is a highly flammable material which is why it is used in many applications as fuel. If a significant amount of hydrogen is released into the air (without trapping the hydrogen), hydrogen molecules can easily reach open flames and be ignited.
