Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.055\% 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(CN(Cc1ccccc1Cl)S(=O)(=O)c1ccc(Cl)cc1)N/N=C/c1ccc(C(=O)O)cc1
b: O=[N+]([O-])c1ccc(NCc2ccc3c(c2)OCO3)cc1
c: CCOC(=O)CN1C(=O)/C(=C/c2ccc(Cl)cc2)Oc2ccccc21
d: CC(C)(C)C(=O)OCc1nc(-c2ccc(O)c(O)c2)cs1
Answer: a. O=C(CN(Cc1ccccc1Cl)S(=O)(=O)c1ccc(Cl)cc1)N/N=C/c1ccc(C(=O)O)cc1
