Answer: 4

The correct answer is A (4 servers per cluster) because Snowflake warehouse sizes follow a doubling pattern with each size increment. A Small warehouse has 2 servers per cluster, and a Medium warehouse is the next size up, which doubles the server count to 4. This is confirmed by the community discussion where all comments unanimously select A, with the top-voted comment (6 upvotes) explicitly stating 'With each warehouse size incremental increase everything doubles including cost', and other comments reinforcing this with simple calculations like '2*2=4'.
