Option A seems like the obvious choice to me. Why reinvent the wheel when the primary key is a tried and true distribution column?

Option D sounds interesting, but I'm not sure it's the most efficient approach. Wouldn't the join conditions make the data distribution more complex?

B) Columns with fewer values are suitable as distribution columns, which can ensure that the data distribution is relatively concentrated.

Haha, option C is a joke, right? Using the filter condition as the distribution column? That's like putting the cart before the horse!

I think option B is the best choice here. Columns with fewer values will help distribute the data more evenly across the nodes.
