Answer: C
Water sprinklers, with an automatic power shut-off system,
are accepted as efficient because they can be set to
automatic release without threat to life and water is
environmentally friendly. Sprinklers must be dry pipe to
prevent the risk of leakage. Halon is efficient and
effective as it does not threaten human life, and therefore
can be set to automatic release, but it is environmentally
damaging and very expensive. Water is an acceptable medium
but the pipes should be empty to avoid leakage, so a full
system is not a viable option. Carbon dioxide is accepted as
an environmentally acceptable gas, but it is less efficient
as it cannot be set to automatic release in a staffed site
because it threatens life.
