The correct alternative is B along the diagonal BDIf we placed a unit positve fee at O, resultant force because of the charges placed at A and C is zero and resultant pressure due to  charges placed at B and D is towards D follow me the diagonal line BD. Hence, net pressure is along the diagonal line BD.
