Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.784\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a C=CCOc1ccc(Br)cc1CNCCO.Cl
b COC(=O)c1sc(S(=O)(=O)N2CCN(c3ccccc3)CC2)c(C(=O)OC)c1C
c COc1ccc(/C=C/c2ccc3c(Br)ccc(O)c3n2)cc1
d O=C(CCCCl)OCc1cn(-c2ccc(Cl)cc2)nn1
e CC(Oc1cccc(Cl)c1)C(=O)Nc1ccccc1C(=O)N1CCCCC1
Answer: a. C=CCOc1ccc(Br)cc1CNCCO.Cl
