The correct three options are B, C and E and they are the three most commonly selected. However options C and E are selected more frequently than option B. The two incorrect responses are selected an approproximately equal number of times – perhaps due to guessing; this question is in formative-only use.
Things get more interesting when you just look at responses from students who use all three responses before getting the question right – or who fail to get it right at all. Whilst 69.2% of these responses include Option C and 65.1% include Option E, only 56.4% include Option B – and an almost identical proportion of responses (56.0%) include the incorrect Option A. So leading and trailing zeroes cause problems.
