Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 3.603\% 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] COc1ccc(S(=O)(=O)/C(C#N)=C/Nc2ccccc2F)cc1
[b] S=c1nccc(-c2ccc3c(c2)CCO3)[nH]1
[c] Cc1ccc(-c2n[nH]c(=O)c3ccccc23)cc1S(=O)(=O)NC(C)(C)C
[d] COc1ccc(NC(=O)CSc2nnc(N)s2)c([N+](=O)[O-])c1
Answer: b. S=c1nccc(-c2ccc3c(c2)CCO3)[nH]1
