Task: Answer the multiple choice question.
Question: Which drug has a 3.090\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a CN(C)/C=C/C(=O)c1cnc2n(c1=O)CCS2
b O=C(O)c1oc2ccccc2c1CSc1ccc(Cl)cc1
c N#C/C(=C/c1ccc(CNC(=O)C(=O)Nc2cc(Cl)cc(Cl)c2)o1)C(=O)NCc1cccnc1
d C(=C/c1ccccc1)\C=N\N1CCN(c2ccccn2)CC1
e CCOC(=O)c1[nH]ncc1[C@@H]1C[C@H]2CN(Cc3cccc(Cl)c3)C(=O)[C@]23CCCN13
Answer: a. CN(C)/C=C/C(=O)c1cnc2n(c1=O)CCS2
