The strange shrimp is a large extinct invertebrate marine animal that is currently the largest known Cambrian animal. Fossils show that this animal has more than a dozen rows of teeth, 25 cm in diameter, and 10 cm in length.5 cm thick. It is speculated that the body length of the odd shrimp may exceed 2 meters. Which of the following, if true, would best support the above speculation? ['Marine shrimp food was abundant during the Cambrian.', '5 cm diameter giant mouth shrimp can prey on any large creature of the time.', 'For large invertebrates, the more teeth the longer the body.', 'The marine shrimp in the Cambrian period had a relatively fixed proportion of teeth and body length.']
