The text explicitly details the setup for a tangible condition in a functional analysis were going to give access to only the preferred tangible adult attention and neutral or moderately preferred toys and then were going to remove the preferred tangible occasionally This precise configuration is crucial It ensures that the client has initial access to the presumed reinforcer preferred tangible along with typical environmental components like adult attention and other nontarget items before the tangible is withdrawn to evoke the problem behavior This systematic manipulation allows the analyst to determine if obtaining the tangible is indeed the function of the behavior Option A is incorrect because it omits adult attention and other toys and suggests contingent removal which is not how the baseline access is established or removed occasionally to test the condition as described Option C inaccurately describes the initial access and states removal only upon behavior which is a specific form of contingent presentation not the general tangible condition described Option D is incorrect as the tangible must be removed at times to test its function and other highly preferred items would confound the specific tangible being tested
