Answer: Using a larger virtual warehouse

The correct answer is A because using a larger virtual warehouse increases the available memory and local disk space for query operations, which directly reduces the need for data spilling. This is supported by Snowflake documentation and community consensus, where spilling occurs when memory is insufficient for intermediate results, leading to performance degradation. Option B (increasing timeout limit) does not address memory constraints causing spilling. Option C (increasing remote storage) is counterproductive as it relates to remote spilling, which is a consequence to avoid, not a solution. Option D (using CTE instead of temporary table) may optimize query structure but does not inherently resolve memory limitations that lead to spilling.
