If the Assertion is correct but Reason is incorrect.

(C) Deep sea divers use a mixture of $He$ and $O_2$ for respiration because $He$ is much less soluble in blood than $N_2$.This prevents the formation of bubbles of $N_2$ in the blood when the diver ascends to the surface,a condition known as decompression sickness or 'bends'.Therefore,the Assertion is correct,but the Reason is incorrect because $He$ is actually sparingly soluble in blood.
