Task: Answer the multiple-choice question.
Question: Which compound exhibits a -5.674% 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: O/N=C1\CCc2cc(Cl)ccc21
b: Cc1c(NC(=O)CSc2ncccn2)c(=O)n(-c2ccccc2)n1C
c: O=C(OCCc1cc2ccccc2c(=O)o1)c1cccc(Br)c1
d: CCCOC(=O)c1ccc(NC(=O)C2CCCO2)cc1
e: O=c1c(C=Nc2ccc(Oc3ccccc3)cc2)c[nH]n1-c1cccc(Cl)n1
Answer: a. O/N=C1\CCc2cc(Cl)ccc21
