select one:

○ b. safety device for excessive internal pressure to be released

Explanation:

Fusible plugs in acetylene cylinders are safety devices. They melt at a certain temperature to release excessive internal pressure, preventing dangerous situations. Option a is incorrect as they don't relate to gas flow from the valve. Option c is about draining water, not fusible plugs. Option d is wrong as they aren't for filling tanks. So the correct answer is b.
