Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.489\% 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: Cc1cc2nc(C)n(CCCNC(=O)Nc3ccc(F)cc3)c2cc1C
b: CCOc1cc(S(=O)(=O)Nc2ncn[nH]2)ccc1Br
c: Br.O=C(Cn1c(NCCO)nc2ccccc21)c1ccc(Cl)cc1
d: O=C(O)C1Nc2c(Cl)cc(Cl)c(Cl)c2C2C=CCC12
Answer: c. Br.O=C(Cn1c(NCCO)nc2ccccc21)c1ccc(Cl)cc1
