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?

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.
