What is the relation of closed slots with leakage reactance and overload capacity?

• A. closed slots give high leakage reactance, and increases the overload capacity
• B. closed slots give high leakage reactance, and decreases the overload capacity
• C. closed slots give low leakage reactance, and decreases the overload capacity
• D. closed slots give low leakage reactance, and increases the overload capacity
