Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 0.747\% 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 other words.
Options:
a: S=c1[nH]nc(-c2cc(-c3ccccc3)n[nH]2)n1/N=C/c1c(Cl)cccc1Cl
b: O=C(Cc1ccc(S(=O)(=O)N2CCOCC2)s1)N1CCN(c2cccc(C(F)(F)F)c2)CC1
c: Cc1cc(C)c(S(=O)(=O)n2c([N+](=O)[O-])cnc2C)c(C)c1
d: CCOC(=O)c1c(NC(=O)CSc2ncn[nH]2)sc(C(=O)N(C)C)c1C
Answer: b. O=C(Cc1ccc(S(=O)(=O)N2CCOCC2)s1)N1CCN(c2cccc(C(F)(F)F)c2)CC1
