Answer: c
Explanation:
ABHAY is an advanced Active-cum-Passive integrated SONAR system designed and developed for the smaller platforms such as shallow water crafts and coastal surveillance/patrol vessels.
HUMSA-UG has been designed for upgrading the existing HUMSA SONAR system of the Indian Naval platforms and AIDSS is a distress SONAR is an Emergency Sound Signalling Device which is used to indicate that a submarine is in distress and enable quick rescue and salvage.
NACS on the other hand will determine the in-situ performance of the SONAR systems which are used to find the frequency-dependent 3-D transmission and reception characteristics of the SONAR. It is also used to measure the magnitude and phase characteristics of the SONAR transmission and reception electronics and the transducers.

Characteristics of the sonar systems developed by DRDO:
The correct characteristic of the sonar systems developed by DRDO is option 'C', which states that AIDSS is used to indicate that a submarine is in distress and enable quick rescue. Let's understand why this is the correct answer.
1. ABHAY:
- ABHAY is a compact hull-mounted sonar system developed by DRDO.
- It is designed for smaller platforms such as frigates, corvettes, and shallow water crafts.
- ABHAY is capable of detecting, localizing, and tracking underwater targets.
- It enhances the underwater surveillance capability of these smaller platforms by providing real-time information about underwater threats.
- However, option 'A' is incorrect because ABHAY is specifically designed for smaller platforms, not large platform systems like deep waters.
2. NACS:
- NACS stands for the Naval Acoustic Characterization System.
- It is a facility developed by DRDO to determine the ex-situ performance of sonar systems.
- NACS allows the evaluation and characterization of sonar systems under controlled conditions.
- It helps in testing and validating the performance of sonar systems before their deployment.
- However, option 'B' is incorrect because NACS is a facility used for evaluating sonar systems, not a sonar system itself.
3. AIDSS:
- AIDSS stands for Automatic Identification System for Distress Submarine Sonar.
- It is an indigenous sonar system developed by DRDO.
- AIDSS is specifically designed to detect distress signals from submarines and enable quick rescue operations.
- It helps in identifying submarines in distress and provides crucial information for initiating timely rescue missions.
- This capability enhances the safety and survivability of submarines and their crew members.
- Option 'C' is correct because AIDSS is indeed used to indicate that a submarine is in distress and enable quick rescue.
Therefore, the correct characteristic of the sonar systems developed by DRDO is option 'C' - AIDSS is used to indicate that a submarine is in distress and enable quick rescue.
