Beliving that her grandmother is hearing-impared, sharon typicallt speaks very slowly and loudly to her. actually, her grandmother can hear quite well bur she naturally matchers her speaking rythms to sharon's, which leads sharon to speak even more slowly and loudly, and the spiral continues. this is an example of:
(a)-overaccommodation
(b)-social equilibrium theory
(c)-patterned response theory
(d)-divergence

Option B. The example given can be explained under the social equilibrium theory, because both parts are doing their efforts to balance the dynamic between them: Sharon thinks thata her grandmother needs more volume to hear then proceeds to level up her; consequently her grandmother, as she raised her voice, does the same, and so on.
