Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.135\% 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 Cc1cc(SCC(=O)OCC(=O)NCc2ccco2)c(C)cc1Br
b CCOC(=O)C1=C(c2ccccc2)NC(=S)NC1c1cc([N+](=O)[O-])ccc1OC
c CCC1C(=O)CC(c2ccco2)NC1c1ccco1
d O=C(O)CCn1cc(/C=C\C(=O)c2ccc(Cl)cc2)c(-c2cccc(Br)c2)n1
Answer: a. Cc1cc(SCC(=O)OCC(=O)NCc2ccco2)c(C)cc1Br
