   This option includes statement 3, which is incorrect as the standard was developed natively by Indian scientific agencies without the specific foreign collaboration mentioned.

3. C

   1 and 2 only. Statement 1 is correct as the Bureau of Indian Standards introduced the national standard for bomb disposal systems designated as IS 19445 : 2025. Statement 2 is correct as this standard aims to ensure uniformity, quality, and interoperability of bomb disposal equipment across different security and law enforcement agencies.

   This option is incorrect because it misses statement 2, which is also a valid feature of the newly introduced standard regarding equipment interoperability across agencies.

Summary. Official key is (c) because statements 1 and 2 correctly identify the newly introduced BIS standard designation IS 19445 : 2025 and its objective of enhancing inter-agency equipment interoperability, while statement 3 is incorrect regarding its development origin.
