Task: Answer the multiple choice question.
Query: Which drug has a 19.892% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a) O=C(N/N=C/c1ccc([N+](=O)[O-])o1)C1CC1
b) C[S+](CC[C@H](N)C(=O)O)C[C@H]1O[C@@H](n2cnc3c(N)ncnc32)[C@H](O)[C@@H]1O.[Cl-]
c) Cc1ccn2c(/C=N/OCc3ccc(F)cc3)c(-c3ccc(Cl)cc3)nc2c1
d) CCc1ccc(NC(=O)CCCn2nc(CC)n3c(cc4occc43)c2=O)cc1
e) Cc1cccc(C)c1N1C(=O)CC(N2CCSCC2)C1=O
Answer: a. O=C(N/N=C/c1ccc([N+](=O)[O-])o1)C1CC1
