A) NO CHANGE B) similar to that of human hunters, C) similar to those of human hunters, D) like human hunters,

Read the incomplete sentence and try to understand the context and the meaning of the sentence. Here, the sentence is not given, so try to imagine a sentence where one of these choices would fit in. For example, imagine the following sentence: "The hunting techniques of the wild animals are ___."

Assess each option to see which one fits best in the context of the sentence. Check the grammar and phrasing of each option. A) NO CHANGE: Since there is no given sentence, this option is irrelevant. So, we can eliminate this option. B) similar to that of human hunters: This option compares the hunting techniques of the wild animals to those of human hunters. The word "that" here refers to a singular thing; however, we are comparing techniques, which is plural. Therefore, this option is incorrect. C) similar to those of human hunters: This option also compares the hunting techniques of the wild animals to those of human hunters. The word "those" here refers to a plural thing, which is correct as we are comparing techniques. Therefore, this option seems to be the correct one. D) like human hunters: This phrase compares the wild animals themselves to human hunters, but we need to compare the hunting techniques. So, this option is incorrect.

Based on the assessment in step 2, the most appropriate option is C) similar to those of human hunters. This option has the correct grammatical structure and appropriately compares the hunting techniques of the wild animals to those of human hunters.
