Task: Answer the multiple choice question.
Question: Which drug has a 13.627\% 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. N#C/C(=C\c1ccccc1)C(=O)N1CCN(c2ccccc2F)CC1
b. COc1c(-c2ccc([N+](=O)[O-])cc2[N+](=O)[O-])c(=O)n(C)c(=O)n1C
c. CC1CCN(C(=O)CSc2nc(N)c(NC(=O)c3ccccc3)c(=O)[nH]2)CC1
d. Cn1c(=O)oc2cc(S(=O)(=O)N3CCc4ccccc43)ccc21
Answer: b. COc1c(-c2ccc([N+](=O)[O-])cc2[N+](=O)[O-])c(=O)n(C)c(=O)n1C
