The question asks which summit hosted by the Ministry of Ports, Shipping and Waterways was used to mark Chabahar Day, so the focus should be on which of these four events is actually organised by that ministry.
The first three summits are all real events but none of them belong to the ports and shipping ministry, while the Maritime India Summit is exactly the ministry's own platform, which is where Chabahar Day was marked.
So the correct answer is Maritime India Summit.
This question stacks two factual claims about Chabahar Port and asks which combination is correct, so each individual claim needs to be checked before looking at the combined options.
Because the location claim and the coastline-length claim are each independently correct, the option that says both captures the full picture, while none of the above contradicts the two facts already established.
So the correct answer is Both (A) and (B).
This question lists three separate claims about what Chabahar Port does and asks which are actually true, so each claim deserves its own check before deciding on all of the above.
None of the three individual claims contradicts what Chabahar Port actually does, so picking any single one of them would leave out equally valid facts.
So the correct answer is All of the above.
The question is about which three countries actually signed the Chabahar trilateral agreement, so matching the countries in each option to the real signatories settles it.
Only the India-Iran-Afghanistan combination matches the real signatories; the other three options each substitute in a country that was never actually party to this specific agreement.
So the correct answer is India-Iran-Afghanistan.
The question asks for the name of the Special Purpose Vehicle set up to develop and manage the Shahid Beheshti Port at Chabahar, so each option needs to be checked against what that SPV is actually called.
The first, second and fourth options each name a real or plausible-sounding company, but none of them is the entity actually running Shahid Beheshti Port; India Ports Global Limited is the SPV created specifically for that purpose.
So the correct answer is India Ports Global Limited.
