which detail should be removed from the summary?

• ○ however, giant squids can grow up to 160 feet long.
• ○ additionally, oarfish can grow up to 50 feet long.
• ○ they are very interesting to look at.
• ○ a sick oarfish may surface and be mistaken for a giant sea serpent.

Explanation:

The summary is about real - life sea monsters and focuses on the characteristics (like size, behavior related to being mistaken for sea serpents) of sea creatures that could be considered sea monsters. The detail "They are very interesting to look at" is a subjective opinion about oarfish's appearance and doesn't relate to the topic of sea monsters (their size, behavior that makes them seem like monsters, or potential to be new discoveries related to sea monsters). The other options provide information about the size of sea creatures (which is relevant to being a "sea monster" in terms of scale) or how oarfish can be mistaken for a sea serpent (relevant to the sea monster theme).

Answer:

C. They are very interesting to look at.
