Problem statement: Answer the multiple choice question.
Question: Which drug has a 9.991\% 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, or d without using any additional words.
Options:
a: CCCCCCCCN[C@H](C)[C@@H](O)c1ccc(SC(C)C)cc1
b: Cc1cc(C(=O)NC(CC(C)C)C(=O)O)cc(C)c1[N+](=O)[O-]
c: Cc1cc(/C=C2\NC(=O)NC2=O)c(C)n1-c1cccnc1
d: CC1CCCCN1C(=O)CSc1nnc(-c2cccnc2)n1C1CCCCC1
Answer: b. Cc1cc(C(=O)NC(CC(C)C)C(=O)O)cc(C)c1[N+](=O)[O-]
