Task: Answer the multiple choice question.
Question: Which drug has a -0.274% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a COC1=C/C(=C/c2c(N)n3c(-c4ccccc4)csc3nc2=O)C=CC1=O
b CN(C)C(=O)c1c([N+](=O)[O-])ncn1C
c CC(C)(C)c1nc[nH]c(=O)c1Br
d COc1ccccc1-n1ccnc(SCC(=O)NCCc2ccccc2)c1=O
e COCCNC(=O)c1onc(CSc2ccccc2)c1C(=O)O
Answer: c. CC(C)(C)c1nc[nH]c(=O)c1Br
