Step 1: Definition of Pratishakhya.
Pratishakhya texts are phonetic guides associated with each Veda.
They elucidate rules for pronunciation, euphonic combinations (sandhi), intonation, and the prescribed style of reciting Vedic mantras.
Step 2: Pratishakhyas of the Samaveda.
The Samaveda is accompanied by two significant Pratishakhya texts:
1. Pushpasutra (also known as Pushpasutram).
2. Riktantra.
These texts specifically address the phonetic nuances and chanting methodologies characteristic of the Samaveda.
Step 3: Exclusion of Incorrect Options.
- (C) Vajasaneyi Pratishakhya: This text pertains to the Shukla Yajurveda, not the Samaveda.
- (D) Rik Pratishakhya: This text is associated with the Rigveda, not the Samaveda.
Step 4: Final Determination.
Consequently, the two Pratishakhyas belonging to the Samaveda are identified as Pushpasutram and Riktantram.
