Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.424% human ether-à-go-go related gene (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 additional words.
Options:
a) O=c1oc2ccccc2nc1/C=C(\O)c1ccc(Br)cc1
b) O=C(c1ccco1)N1CCN(c2ncnc3c2oc2ccccc23)CC1
c) O=c1c2sccc2nc(SCc2cc(=O)n3ccccc3n2)n1-c1ccc(Br)cc1
d) COc1ccc(S(=O)(=O)N2CCOCC2)cc1NS(=O)(=O)/C=C/c1ccccc1
e) CC(=O)Nc1c2c3c(cccc3n(C)c1=O)C(=O)c1ccccc1-2
Answer: a. O=c1oc2ccccc2nc1/C=C(\O)c1ccc(Br)cc1
