Correct Answer : INS Sarvekshak
Indian Navy’s Hydrographic Survey Ship INS Sarvekshak successfully completed survey action around the site of ill-fated MV X-Press Pearl on July 2 and handed over the survey data to the Sri Lankan authorities. The X-Press Pearl reported an onboard acid leak and caught fire just as it was due to enter the Colombo harbour on May 20. The fire was put out only after 13 days.
