Explanatory Answer
According to the passage, when the cephalopod wants to change colour, the brain carries an electrical impulse through the nerve to the radial muscles on their pigment sacs, thereby pulling open the sacs to display red, yellow and brown colours on their skin. So, if the radial muscle movement is hindered (option A), or if the transmission of neural signals is affected (option B) the camouflaging adeptness of cephalopods will be weakened. So too, if light reflects a different set of colours - red, green, and yellow, instead of red, yellow and brown- at the depths in which cephalopods reside, then they will not be able to camouflage effectively. So, option C also weakens the camouflaging adeptness of cephalopods.
The passage does not talk about the number of chromatophores, iridophores and leucophores cephalopods have. So, it is not possible to say, based on the contents of the passage, whether option D, if true, weakens the camouflaging adeptness of cephalopods. So, this is the answer choice we are looking for.
