If you do not like the options provided and want to express that "b" and "d" are not the answers, you can simply leave those spaces blank or write "none of the above." This signifies that you are aware those options are incorrect but do not have an alternative answer to provide. So in this case, you can choose option "a" as the correct answer and leave the other options blank or write "none of the above."
