Task: Answer the multiple choice question.
Question: Which drug exhibits a -63.446% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(O)c1c[nH]c(=S)n1-c1ccc(F)cc1
b: O=C(Nc1nnc(-c2ccco2)o1)c1cccc(Cl)c1
c: O=C(CCN1C(=O)/C(=C\c2cccc(Br)c2)SC1=S)NCCCN1CCOCC1
d: Cc1nc2nc(C)c(CCC(=O)NCc3ccc4c(c3)OCO4)c(C)n2n1
Answer: c. O=C(CCN1C(=O)/C(=C\c2cccc(Br)c2)SC1=S)NCCCN1CCOCC1
