Question

Assertion (A): Violin and Dilruba both instruments are played by Plectrum.
Reason (R): The Violin and Dilruba have 6 main strings.

Accepted Answer

Option 4 is the correct answer, which states that both Assertion (A) and Reason (R) are false. Let's examine why this is the case:

1. **Assertion (A): Violin and Dilruba both instruments are played by Plectrum.**
   - This assertion is false. The violin is played using a bow, which is drawn across the strings to produce sound. It is not played with a plectrum. Similarly, the Dilruba is also played with a bow, not a plectrum. The Dilruba is a traditional Indian string instrument that is bowed, much like the violin. Therefore, the assertion that both instruments are played by a plectrum is incorrect.

2. **Reason (R): The Violin and Dilruba have 6 main strings.**
   - This reason is also false. The standard violin typically has four strings, tuned to G, D, A, and E. The Dilruba, on the other hand, usually has around 18 to 20 strings, but only a few of these are main playing strings, with the rest being sympathetic strings. The main playing strings on a Dilruba are typically four. Therefore, the statement that both instruments have six main strings is incorrect.

Now, let's explain why each of the other options is incorrect:

1. **Option 1: Only (A) is true.**
   - This option is incorrect because, as explained above, the assertion that both the violin and Dilruba are played by a plectrum is false. Both instruments are played with a bow.

2. **Option 2: Only (R) is true.**
   - This option is incorrect because the reason provided is false. Neither the violin nor the Dilruba has six main strings. The violin has four, and the Dilruba typically has four main playing strings, with additional sympathetic strings.

3. **Option 3: (A) and (R) both are true.**
   - This option is incorrect because both the assertion and the reason are false. The assertion about the method of playing and the reason regarding the number of strings are both factually incorrect.

In conclusion, Option 4 is the correct answer because both the assertion and the reason provided in the question are false based on factual information about the violin and Dilruba.
