Which of the following is/are the preventions of galvanic corrosion? Correct Answer Avoid the unfavorable area effect of a small anode and large cathode and select the close combination of metals in galvanic series

In industrial applications avoiding a dissimilar metal combination is impossible. But it can be minimized by avoiding the unfavorable area effect, selecting the close combination of metals. Proper material selection and regular inspection are other preventive measures.
