Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.670\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CN1CCC(OC(=O)c2ccccc2Cl)CC1.Cl
b O=C(O)C(=O)O.O=C(c1ccccc1)c1ccc(OCCOCCN2CCN(Cc3ccccc3)CC2)cc1
c O=C(CN1CCN(c2cccc(Cl)c2)CC1)Nc1ccc(S(=O)(=O)N2CCOCC2)cc1
d O=C(COc1cccc2cccnc12)NNC(=O)Nc1ccccc1
Answer: a. CN1CCC(OC(=O)c2ccccc2Cl)CC1.Cl
