Explanation:

The problem involves classifying or comparing animal characteristics, which falls under Biology (a subfield of Natural Science). The table lists traits for different species (Mesopithecus, lynx, douc), and we analyze the checkboxes. For "four limbs", Mesopithecus has a check, but lynx and douc (both animals) also have four limbs, so the checkboxes for lynx and douc in "four limbs" should likely be checked (assuming the table is about identifying shared traits; lynx and douc are tetrapods with four limbs).

Answer:

For the "four limbs" row, the checkboxes for lynx and douc should be checked (i.e., the boxes under "lynx" and "douc" in the "four limbs" row should have checks, similar to Mesopithecus). If the question was about identifying a trait all three share, "four limbs" is a trait (as lynx, douc, and Mesopithecus are vertebrates with four limbs), so the correct marking is checking lynx and douc in "four limbs".
