Task: Answer the multiple choice question.
Query: Which drug exhibits a -1.863% 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 additional words.
Options:
a. O=c1[nH]c(/C=C/c2cccc([N+](=O)[O-])c2)c([N+](=O)[O-])c(=O)[nH]1
b. CC(=O)Nc1cc2c(cc1C(=O)c1ccccc1)OCCO2
c. Cc1noc2ncnc(Sc3ccccc3Cl)c12
d. O=C(COc1ccc(Br)cc1F)N1CCN(c2ncccn2)CC1
Answer: b. CC(=O)Nc1cc2c(cc1C(=O)c1ccccc1)OCCO2
