Option B looks good to me. Efficient and straightforward. Though I have to admit, I'm a bit disappointed they didn't include a 'Bling' color grade. That would have been the ultimate diamond experience!

I'm going with option B too. Gotta love those concise test sets that still hit the key partitions. Although, I do wonder if the diamond retailer has considered adding a 'Glitter' color grade. That would really spice things up!

Hmm, I'm not sure. Option A seems to cover a wide range of the valid domain, but it's a bit overkill. Maybe option B is the most efficient solution.

I think option A covers too many characters.

But option A covers a wider range of characters, which could be more comprehensive.

Okay, this question is asking about the best equivalence partitioning coverage for the new diamond color grading system. I think option B covers the most important partition, the valid domain from D to Z.
