D Correct answer
Explanation

SQL statement tuning centers on optimization quality - whether the query optimizer finds an efficient execution plan. The number of CPUs (A) and degree of parallelism (B) are system resources, not tuning considerations. Bitmap indexes (C) are specific access methods, not general tuning principles. Optimization quality directly affects performance.
