Select the correct answer using the code given below :

Based on technical specifications of these firearms:

• Statement 1 is correct: The AK-47 (Avtomat Kalashnikova) is designed to chamber the 7.62 × 39 mm cartridge.
• Statement 2 is correct: The INSAS (Indian Small Arms System) rifle, developed by DRDO, uses the 5.56 × 45 mm NATO standard ammunition.
• Statement 3 is incorrect: The INSAS rifle is generally longer (approximately 960 mm) compared to the AK-47 (approximately 880 mm).
• Statement 4 is generally considered incorrect: While weights vary by variant, the standard INSAS rifle (approx. 4.15 kg empty) is often heavier than the widely used AKM variant (approx. 3.1 kg) or comparable to the original AK-47.

Since statements 1 and 2 are definitive technical facts and statement 3 is clearly false, Option B is the most accurate choice.
