Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 1.364\% 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 other words.
Options:
a: COc1ccc(N2C(=O)C(Cl)=C(Nc3ccc(OC)cc3OC)C2=O)cc1
b: O=C(O)c1cccc(CN2C(=O)S/C(=C/c3cccc([N+](=O)[O-])c3)C2=O)c1
c: CCCC(=O)O[C@]1(C(=O)CCl)[C@@H](C)C[C@H]2[C@@H]3CCC4=CC(=O)C=C[C@]4(C)[C@@]3(F)C(=O)C[C@@]21C
d: C=CCn1c(-c2ccccc2[N+](=O)[O-])n[nH]c1=S
