"Equal Width with Custom Start and Stop binning mode" only do binning but with goal it's require normalized as well as binning problem. Thus that's incorrect @Askme101 provide possible answer using MDL is correct one https://docs.microsoft.com/en-us/azure/machine-learning/studio-module-reference/group-data-into-bins

Selected Answer: B
Should use Quantiles. The quantile method assigns values to bins based on percentile ranks, because you need to normalize, while Equal Width puts the data into each bin at the same interval between starting and ending values.

Entropy MDL may be the best answer, but the question is whether this solution meets the goal stated. The solution stated may not be optimal but does bin the values.

Entropy MDL is not available in designer. The answer applies only to studio(classic). If asked in Designer context, I think the answer is actually Yes.

'A' is correct per the link: "Equal Width with Custom Start and Stop: This method is like the Equal Width option, but you can specify both lower and upper bin boundaries."
