The best option for revising the underlined sentences to include more precise language and vocabulary is:
A. An octopus can almost instantaneously match the colors, patterns, and textures of its surroundings. Predators such as dolphins, eels, and sharks swim by without even noticing them!
This option uses specific terms (like "match the colors, patterns, and textures") and provides a clearer, more vivid description of the octopus's camouflage ability, enhancing the precision of the information presented.
