Answer & Explanation
The correct answer is Option B: To prevent agitation of the oil and spreading the fire.
When applying foam to an oil fire, banking it off a bulkhead prevents the direct force of the foam stream from agitating the oil surface. Agitation can spread the burning oil and potentially worsen the fire, hindering extinguishment.
