The deep sea remains one of Earth's least explored frontiers, harboring creatures that defy conventional biological understanding. Among these are the anglerfish, famed for their bioluminescent lure. This predatory fish, which inhabits the abyssal zone, uses a glowing appendage on its head to attract prey in the perpetual darkness, a hunting strategy that is both ingenious and terrifying. Its unique adaptations highlight the extreme diversity of life in the ocean's depths. Which choice best maintains the sentence's meaning and conforms to the conventions of standard English?

Tactical Insight (Hint 1)

Consider whether the information 'inhabits the abyssal zone' is essential to identify *which* predatory fish is being discussed, or if it merely provides additional, descriptive detail.

Elimination Framework (Hint 2)

Recall the punctuation rules for non-restrictive (non-essential) clauses, especially when they begin with 'which.' How are such clauses typically set off from the rest of the sentence?

⚡ Hack the Test speed shortcut: Use the 'Remove It' Test. For clauses starting with 'which' or 'that,' try mentally removing the clause from the sentence. If the sentence still makes complete sense and retains its core meaning without the clause, then the clause is non-essential (non-restrictive) and *must* be set off by commas. If removing it changes the meaning or makes the sentence unclear, it's essential (restrictive) and should *not* have commas (and typically uses 'that'). Applying this to the sentence: 'This predatory fish [which inhabits the abyssal zone] uses a glowing appendage...' If we remove the bracketed part, we get 'This predatory fish uses a glowing appendage...' This sentence still makes perfect sense, confirming that 'which inhabits the abyssal zone' is non-essential information. Therefore, it requires commas around it, making Option C the clear choice.
