We can fill in the given triplets in the sentence and interpret them to find the one that best conveys the meaning:

• A. In an anthropocentric construct, animals are no more than property to human beings. Therefore, the concepts of ‘humane' treatment and ‘necessary‘ comfort are economic in nature. The idea that killing animals is not a serious issue as long as animals are not made to suffer rests somewhat on the widely accepted idea that animals do not have a right to life.
• B. In an anthropocentric belief, animals are no more than property to human beings. Therefore, the concepts of ‘humane' treatment and ‘necessary‘ well being are economic in nature. The idea that killing animals is not a serious issue as long as animals are not made to suffer rests partially on the widely accepted idea that animals do not have a right to life.
• C. In an anthropocentric worldview, animals are no more than property to human beings. Therefore, the concepts of ‘humane' treatment and ‘necessary‘ suffering are economic in nature. The idea that killing animals is not a serious issue as long as animals are not made to suffer rests explicitly on the widely accepted idea that animals do not have a right to life.
• D. In an anthropocentric universe, animals are no more than property to human beings. Therefore, the concepts of ‘humane' treatment and ‘necessary‘ gain are economic in nature. The idea that killing animals is not a serious issue as long as animals are not made to suffer rests entirely on the widely accepted idea that animals do not have a right to life.
  

Out of the four given options, option C fits the sentence best. Anthropocentric worldview refers to a perception of the world that puts humans at the centre. 'Suffering' also fits the contrast against 'humane treatment.' 'Explicitly' as an adverb points out the specificity of the proposition that animals do not have a right to life.
