Show answer

Answer: C. Statement 1 is correct: the standard is IS 19445:2025, released by BIS in December 2025. Statement 2 is correct: one national test standard for items like bomb blankets and baskets lets the armed forces, CAPFs and state police compare and use equipment on the same basis. Statement 3 is wrong: it was developed by a BIS panel convened by TBRL (DRDO), with no Russian or other foreign partner. So 1 and 2 only.

Watch for: India-Russia defence ties make the Russian collaboration claim look believable.

Why the other options are wrong
  • A. Wrong because the Russian collaboration in statement 3 is false.
  • B. Wrong because statement 3 is false and statement 1 is left out.
  • D. Wrong because statement 2 is also correct.
