Option (b) is logically valid as it is directly supported by the information in the passage. The passage clearly states that the court ruled it did not have jurisdiction to hear the case on the grounds that the vessel sank in international waters.
Option (a) is incorrect because the passage does not mention anything about the court believing the men were innocent. The case was dropped due to jurisdictional issues, not because of a judgment on their innocence and unlawful treatment of the accused.
Option (c) is incorrect because there is no information in the passage about transferring the case to another court. The passage only states that the court in Kalamata ruled it did not have jurisdiction.
The passage indicates that there were cheers among protesters when the decision to drop the case was announced, suggesting they were pleased, not disappointed. So, option (d) is incorrect.
Option (e) is incorrect because the passage states that the evidence had been contradicted by at least six survivors, who claimed the coastguard caused the boat to capsize and pressured them to frame the Egyptians.
Hence, the correct answer is option (b).
