Task: Answer the multiple choice question.
Question: Which drug has a 12.832\% 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=C(O)Cc1cccc2ccccc12
[b] COc1cccc(OCC(=O)Nc2cc(Cl)ccc2Oc2ccccc2)c1
[c] CS/C(=C\[N+](=O)[O-])Nc1ccc(OC(F)(F)F)cc1
[d] COc1cccc(NC(=O)c2ccc(S(=O)(=O)N3CCCCC3)cc2)c1
Answer: a. O=C(O)Cc1cccc2ccccc12
