In Sāṅkhya philosophy, bāhyakaraṇa (external instruments) are:
1. The five sensory organs (Jñānendriyas): Eyes, ears, nose, tongue, and skin (A).
2. The five motor organs (Karmendriyas): Hands, feet, speech, excretion, and reproduction (B).
Incorrect options:
- (C): Mind (it{Manas}) is considered an internal organ, not an external one.
- (D): Includes both it{Jñānendriyas} and it{Manas}, but it{Manas} is not part of it{bāhyakaraṇa}.
Thus, the correct answers are (A, B).
