Divide dielectrics into 4 different capacitors respectively C1,C2,C3,C4.C1=k1*A*€/(d÷2)C2={A÷3}*€*K2/(d÷2)AND C3 AND C4 ARE SAME AS C2 WITH DIFFERENT DIELECTRIC CONSTANT.C2,C3,C4 ARE IN PARALLEL SO EFFECTIVE CAPACITANCE=C2+C3+C4THIS CAPACITANCE IS IN SERIES WITH C1 . THEREFORE YOU GET OPTION ONE AS ANSWER
