What is the formula for the area required for the insulated conductors?

• A. area required for the insulated conductors = total number of conductors per slot * 0.785 / diameter of insulated conductor2
• B. area required for the insulated conductors = total number of conductors per slot / 0.785 * diameter of insulated conductor2
• C. area required for the insulated conductors = total number of conductors per slot * 0.785 * diameter of insulated conductor2
• D. area required for the insulated conductors = 1/total number of conductors per slot * 0.785 * diameter of insulated conductor2
