Step 1: Understanding the Concept:
This question tests technical knowledge of Sanskrit phonetics as preserved in the Paniniya Shiksha. Assertion (A) concerns the classification and count of consonants, while Reason (R) concerns the metaphorical measurement of vowel duration (Matras). Accuracy in these counts and analogies is vital for the study of the Shiksha Vedanga.
Step 2: Detailed Explanation:
Let's analyze both statements:
Analysis of Assertion (A):
In Sanskrit grammar and the Paniniya Shiksha, the consonants from 'k' to 'm' are called 'Sparsha' (contacts/stops) because they involve a complete contact of the tongue with a place of articulation. There are five groups (vargas) of five letters each (ka-varga, cha-varga, ta-varga, ta-varga, pa-varga).
$5 \times 5 = 25$.
The famous rule is: "kādayo māvasānāḥ sparśāḥ" (Those starting with 'ka' and ending with 'ma' are Sparsha). Thus, Assertion (A) is factually correct.
Analysis of Reason (R):
The Paniniya Shiksha (Verse 33) provides an analogy for vowel durations using bird calls:
- Chasha (Blue Jay) calls with one matra (Hrasva).
- Vayasa (Crow) calls with two matras (Dirgha).
- Shikhi (Peacock) calls with three matras (Pluta).
The verse says: "śikhī rauti trimātram tu" (But the peacock cries with three measures). Reason (R) states "Shikhi rauti dvimatram" (two measures), which contradicts the text. Therefore, Reason (R) is factually incorrect.
Conclusion:
Since (A) is true and (R) is false, the correct option is (3). This question requires precise knowledge of the phonetic analogies used in the Shiksha. Students often confuse the Matra counts associated with different animals.
Step 3: Final Answer:
(A) is correct but (R) is incorrect. Therefore, the correct option is (3).
