A.I. Explanation:

Option 1: "The Titanic was raised from the ocean floor."

Explanation: This option is incorrect because the text does not mention the Titanic being raised from the ocean floor. Instead, it states that the Titanic was first glimpsed in 1985, but it does not indicate any recovery efforts. Therefore, this option presents contradictory information.

Option 2: "A memorial service was held at sea for the victims."

Explanation: This option is incorrect as the text does not reference any memorial service being held for the victims of the Titanic. The focus of the text is on the discovery of the wreck, not on commemorative events, making this option not given in the text.

Option 3: "The wreck of the Titanic was first glimpsed by an underwater camera."

Explanation: This option is correct because the text explicitly states that in 1985, the underwater camera carried by the submersible sled Argo provided the first glimpse of the Titanic wreck after nearly 75 years. This aligns perfectly with the main idea of the text regarding the discovery of the Titanic.

Option 4: "The iceberg that sank the Titanic was located."

Explanation: This option is incorrect because the text does not mention the location of the iceberg that sank the Titanic. Instead, it focuses on the discovery of the wreck itself, which is a different event. Thus, this option presents partial information that does not align with the text.
