Final answer:
The word pair that has the same r-controlled ar sound is A. carve/bargain.
Step-by-step explanation:
The word pair that has the same r-controlled ar sound is A. carve/bargain. In both words, the letter 'ar' creates the same sound. In 'carve', the 'r' after the 'a' changes the sound to 'car'.
In 'bargain', the 'r' before the 'ai' also changes the sound to 'bar'.
