Answer:
Option (D).
Step-by-step explanation:
The change in the external and internal environment can be detected by the receptors present on the body surface. These receptors help in detection and maintenance of the body homeostasis by the signal transduction mechanism.
Interoceptors detect the stimuli present within the body and mainly from internal organ and gut. Exteroceptors receive the stimuli by the external environment. Proprioceptor receive the stimuli by change in the body position and movement. All these receptors are involved in the Josh and his friends condition.
Thus, the correct answer is option (D).
