Option B, After Dried
Explanation:
All biological fluids such as blood, semen, saliva etc. are not collected from the crime scene when they are wet or moist. Since, we all aware that all human beings are genetically distinct hence if these fluids are tested after they dry up, no specific impact can occur on the sample and the test result. Also collecting dry sample is much easy and comfortable. The dried samples undergo DNA analysis there by producing a genetic profile which is specific to individuals

Answer:
C. Paleozoic
Explanation:
Trilobites are a group of extinct marine arthropods. Just like many animals from today, including crustaceans, spiders, and insects, they belonged to the phylum Arthropoda. They lived in the Paleozoic era.
We can make this conclusion based on the fact that the period they existed in (from 521 to 250 million years ago) mostly fits the period described as Paleozoic (from 541 to 252 million years ago). However, we can see that they went extinct in the Mesozoic (250 million years ago is more than 252 million years ago). Compared to the entire time they existed, 2 million years is a relatively small amount of time, which makes Paleozoic the correct option.
