Task: Answer the multiple choice question.
Query: Which drug has a -1.691\% 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 other words.
Options:
a. CCOc1ccc(S(=O)(=O)Nc2nc3ccccc3nc2Cl)cc1
b. O=C(CC1SC(=O)N(c2ccccc2)C1=O)Nc1ccc(Br)cc1
c. C=CCn1c(SCC(=O)OCc2ccccc2)nc2c1c(=O)n(C)c(=O)n2C
d. COc1cc(CN(CCc2c(C)[nH]c3ccc(C)cc23)C(=S)NC(C)(C)C)cc(OC)c1OC
e. COc1ccccc1NC(=O)CN1CCN(CC(=O)Nc2ccc(F)cc2)CC1
Answer: a. CCOc1ccc(S(=O)(=O)Nc2nc3ccccc3nc2Cl)cc1
