Lets have a look at each option separately - Option ‘a’: Always asociated with raised uterine size for gestational age. This statement is incorrect as : “The size of the uterus is more than that expected for the period of amenorrhea in 70%, corresponds with the period of amenorrhea in 20% and smaller than the period of amenorrhea in 10%.” Dutta Obs. 7/e, p 193 Option ‘b’: Raised hCG - H. mole is characterised by raised levels of hCG (levels > 105 MIU/ml) Dutta Obs. 7/e, p 193 Option ‘c’: Hysterectomy in selected cases : Management of H.mole :TOC in H. mole – Suction evacuation followed by gentle but thorough currettage. Hysterectomy – It is indicated only in case of :                                  – Female has completed her familyHysterotomy – Indicated in cases complicated by haemorrhage.So, option ‘c’ i.e. hysterectomy is done in selected cases is correct whereas option ‘d’ i.e. chemotherapy is the TOC is incorrect. Option ‘e’: As far as thyrotoxicosis is concerned : It is seen in only 2% cases of H.mole. It is rare (so, option ‘e’ is correct). “Clinically apparent thyrotoxicosis is unusual.” William 23/e, p 260
