a) intangibility

b) professional competence

c) perishability

d) inseparability

Option D                                                          

Explanation: In simple words, inseparability refers to the characteristic of service according to which a service cannot be separated from its service provider. Once the service provider has provided a service the user must consume it and cannot undo its effects whatsoever.

However in case of goods, one can easily replace one in place of other  as per the situation. In the given case, Sean was unsatisfied with the service of doctor but till could not undo it.

Hence the given case depicts inseparability.
