Task: Answer the multiple choice question.
Query: Which drug has a 6.611\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=[N+]([O-])c1cc(Cl)cc(/C=N/Nc2nc3ccccc3s2)c1O
(b) O=C(NC1CCCC1)C(=O)c1c[nH]c2ccccc12
(c) CC1CCc2c(sc3ncn(CCO)c(=O)c23)C1
(d) Cc1oc2cc(O)ccc2c(=O)c1Oc1ccccc1Br
Answer: a. O=[N+]([O-])c1cc(Cl)cc(/C=N/Nc2nc3ccccc3s2)c1O
