Answer: 128

The correct answer is C (128 credits). According to Snowflake documentation, a 3X-Large virtual warehouse consumes 64 credits per hour. Since the warehouse runs continuously for 2 hours, the total credit consumption is 64 credits/hour × 2 hours = 128 credits. The community discussion confirms this calculation with multiple users selecting C and providing the same reasoning, with the highest upvoted comment explicitly stating '64 per hours for 2 hours = 128'. The other options (32, 64, 256) represent incorrect calculations or misunderstanding of the credit consumption rates for different warehouse sizes.
